A Direct Train of Cordite

On 14 July, 1916, the Vice-Admiral Commanding the Battle Cruiser Fleet, Vice-Admiral Sir David Beatty, sent a letter to the Admiralty:

Sir,

Be pleased to lay the following remarks before Their Lordships:-

2. Since the recent Battle of Jutland it has been very strongly brought home to me that I can recall no single instance of a German warship blowing up, as unhappily occurred in the case of "QUEEN MARY", "INVINCIBLE", "INDEFATIGABLE", and "DEFENCE".

3. This fact is the more remarkable since on several occasions German battle-cruisers and light cruisers have been subjected to far heavier punishment by gunfire than was experienced by these three battle-cruisers. As instance, the "BLUCHER", on 24th January, 1915, when lying over practically on her beam ends was repeatedly hit by heavy shell, some of which, entering through the unprotected bottom, must have penetrated to and burst in or near her magazines. Again, a light cruiser on 31st May, 1916, having been reduced to a sinking condition by the fire of the 3rd Battle Cruiser Squadron and 1st Cruiser Squadron, passed the whole length of the Battle Line under heavy fire, and burning ferociously, but yet did not blow up. On 28th August, 1914, the "KOLN" was under the concentrated fire of five battle-cruisers at about 6000 yards for some minutes. She sank, but there was no trace of an explosion. Other instances could be cited, but these are sufficient for the purpose.

4. I have personally, both on 24th August and on May 31st seen high columns of flame rising from German ships, which could only have been caused by magazine fires, yet in no case did I witness any semblance to an explosion to this cause.

5. The immunity of German cruisers of all types to these disastrous explosions may be attributable to the following differences, which I understand exist between British and German methods:-

(a) For 12" guns and below, the propellant is not exposed and fitted with a highly sensitive igniter, is contained either in a light metallic envelope or a brass cylinder. In either case, in all probability, the charge is impervious to flash.

(b) In heavy ships- Adequate protection which ensures the burst of an A.P. shell before it reaches the immediate vicinity of a magazine. There is also the belief, held by many officers, that the turret magazines are placed under the shell rooms and next to the inner bottom.

6. Should these two reasons be held as sufficient to account for the absence of disruptive explosions when German ships are literally riddled by shell fire at close range, there is still required an explanation of how it is possible in German ships for very large cordite fires to arise, and apparently burn out, without any visible explosion. In this connection, on 24th January a turret in the "SEYDLITZ" was seen to be surrounded by sheets of flame, rising as high as her masthead, and obviously due to fire in the magazine. Had such a situation arisen in a British ship, in the light of recent events it seems certain that she would have been totally destroyed in the space of a few moments.

7. From the various reports of eye-witnesses and survivors, the destruction of the "QUEEN MARY" and "INDEFATIGABLE" appears in each case have instantaneously followed their being struck by an accurate salvo. Both ships up to this moment shewed no signs of distress and had received but slight punishment. The extracts from Despatches, given in the Appendix, are of importance since in the case of "QUEEN MARY" and "INVINCIBLE" a hit on, or abreast, "Q" turret was observed immediately before the explosion. A similar explosion under "Q" turret of "LION" was avoided by the presence of mind of the Officer of the Turret, but in this case an interval of 20 to 30 minutes elapsed between the burst of the shell and the resulting explosion of ammunition below the turret. Perhaps the cause of the final explosion in the "AUDACIOUS" has been explained, and might bear some connection to these cases.

8. Consideration of the points I have mentioned leads to the conclusion that either our methods of ship construction are seriously at fault or that the nature of the ammunition we use is not sufficiently stable to ensure safety. The catastrophes which occurred on May 31st must be due to one or both of these causes. From the behaviour of German ships, these are proved not to be insuperable. It is noted that no case has been reported of a British Destroyer blowing up, although several have now been sunk by gunfire.

9. I therefore most strongly urge that it should be accepted that a radical fault does exist, and that the best brains in the country are necessary to assist in its speedy removal in existing ships and its prevention in new construction. To this end I suggest that Committees of the greatest experts should be formed, and no expense or trouble spared to thoroughly investigate the following amongst other points. I assume that the measures taken by the Admiralty since the action are not in any way final or other than temporary expedients; to my mind the cure is farther to seek.

10. Points particularly recommended for investigation:

(a)The position of magazines — whether they should not all be placed as low as possible in a ship, and on the centre line.

(b) The protection of magazines from shell fire and torpedoes. Observing that the penetration of one hot splinter to a magazine may be sufficient to cause explosion of the contents.

(c) The need of additional protection to roof plates, glacis, trunk of all turrets, and particularly of "Q" turret, since most hits occur on this central part of ships.(d) The British design of turret, with sloping front and roof plates, increases the chance of penetration by shell at long range by providing a surface nearer the normal than if the front plates were vertical and the roof plates horizontal.

(e) The provision of a separate explosion trunk from all handing rooms to the upper deck, to provide some egress for gas pressures other than through the trunk and turret.

(f) The design of flash doors throughout 13.5" and 12" turrets appears to have been based only on the necessity of defeating back flame from the gun, which is small in volume and produces no gas pressure comparable with that of a shell burst or ignition of cordite in the turret. The numerous holes in gunhouse and working chamber floors and sides are a decided source of danger.

(g) The abolition of igniters permanently fitted to charges.

(h) The protection of charges by a light metal envelope capable of volatilisation on firing.

(i)The apparent immunity of German nitro-cellulose propellants from explosion by shell fire, as compared with cordite.

(j) The ready communication of explosion from one magazine to another widely separated.

(k) The safety of nose-fuzes in common H.E. shell.

(l) The stowage of shell in bins in gunhouses and working chambers of turrets.

(m) The introduction of the Q.F. principle of Breech Mechanism for all future guns.

 I have the honour to be,

 Sir,

 Your obedient servant,

 David Beatty

Beatty's letter first went to the Permanent Secretary to the Board of Admiralty, Sir W. Graham Greene, who noted on 18 July: "It is presumed that the DNC [Director of Naval Construction] & DNO [Director of Naval Ordnance] will be asked to report on this letter in [the] first place." The letter was next sent to the Third Sea Lord, Rear-Admiral Frederick C. T. Tudor, who forwarded it to the D.N.O. and D.N.C. "For remarks" on 19 July. The D.N.O., Rear-Admiral Morgan Singer, received it on 20 July.

On 3 August Singer wrote:

Submitted:-

While not wishing to minimise in any way the seriousness of the events of 31st May, I am convinced that the blowing up of our ships in that action was caused not so much by the greater inflammability of our propellant as by the system of supply which we unfortunately practised i.e. magazine doors open, lids off powder cases, all cages and waiting positions loaded; thus should a shell burst in working chamber or trunk, as I have no doubt occurred at least in on case "Invincible", there was every possibility of the flash being carried direct to the magazine.

As regards the case of the "Seydlitz", mentioned in paragraph 6 of Vice-Admirals's letter, it was the custom in German turrets (to go by report on "Goeben") to keep charges in ready racks in the turrets, these probably caught fire during the action of 24th January, 1915 and the turret ports &c., forming a good vent the flame would be very visible; the cartridges being protected would not pass the flash to the magazine, I also suggest that the Germans on 24th January, 1915, had good experience of what heavy shell fire meant which we certainly had not, the former have therefore most probably profited by their experience in increasing their deck protection and preventing any accumulation of powder charges.

The Germans use, according to our latest information, a nitro-glycerine powder in their Naval Service somewhat similar to our M.D. powder and we know that in their guns up to 11-inch brass cartridges are used for the rear charge and some sort of metallic envelope which is consumed in the gun and above but I understand that considerable difficulty was experienced with such heavy brass cases in extracting and getting rid of them after firing.

The Vice Admiral appears to think that cordite if ignited in the open or only lightly confined will explode, this is not so, it burns rapidly giving off a large quantity of gas; in the "Lion" the charges did not explode but the evolution of gas was sufficient to carry the flash down the trunk, as the nearest vent, into the shell room igniting some charges in the handing room en route, [underlined in red pencil] had the magazine been open and lids off the powder cases undoubtedly the magazine would have blown up.
Taking the points mentioned in paragraph 3 of Vice-Admiral[']s letter seriatim:

(a) As far as the gun mounting is concerned it would be arranged in new designs for the magazine to be under the shell room.

(b) A constructive question.

(c) The question of roof plates has been dealt with for existing for existing and future turrets.

(d) This is being considered in new designs & in accordance with instructions of 3rd Sea Lord.

(e) The necessity for this is very doubtful but requires consideration.

(f) This no doubt requires consideration[,] it is difficult to arrange a flash door which would always be shut except when the cage is actually passing it; at present flash doors open in one direction and are kept open during the time the G.L. cage is up. In the case of the "Lion" the burst of the shell did not directly ignite the cordite charges, it is impossible to say what did cause them to ignite 20 minutes later, nor is it known why the charges were not sent down as all gear in the working chamber was intact i.e. no vital damage was done in working chamber or to charges by the actual blast of the shell, one flash door was on this occasion open as the cage was up.

(g) Trials have shewn that igniters are very little more inflammable than the cordite itself, and in any case the protecting discs now fitted to igniters afford more protection to the charge en route to the gun than if there were no igniter and no disc.

(h) Requires consideration and research.

(i) As before remarked the apparent immunity mentioned is considered to be due to the protection of charges and care taken to prevent any accumulation, not to the nature of the propellant.

(j) This is not understood

(k) There is a possibility, in shell fuzed with No. 13 fuze, if the fuze were hit fair by a fragment, of the shell detonating; all trotyl shell have No. 45 which has a sealing device, orders have been given to withdraw heavy lyddite common shell as soon as possible.

(l) Orders have been given prohibiting stowage of H.E. Shell in gun houses and working chambers of turrets.

(m) I think that if the point under (h) can be solved it would be the sounder plan than attempting to introduce the Q.F. principle for heavy guns. As regards light guns the objections to the Q.F. Principle are well known and we have experience from 6-inch calibre downwards; I think that adequate protection of the charge from magazine to gun overcomes the danger and risk of bare charges and this can be arranged with some possible loss in rapidity of fire.

Taking Vice Admiral[']s suggestions as a whole there appears to be scope for investigation of several important points, though with the exception of the provision of metal envelopes for charges the points to be dealt with are connected with ship and gun mounting designs.

 D.N.O.

 -3 Aug. 1916

The D.N.C., Eustace H. W. Tennyson d'Eyncourt, responded with a memorandum on 7 October:

Although no German ship has yet been observed to blow up under gun fire in the manner which caused the loss of the British Battle Cruisers, it would appear in view of the definite statements of the Vice Admiral in para. (1) to (4) below, that this is not because the ship's structure has been as badly damaged, or penetrated to the same extent, as British ships have been

(1) - "Blucher" was repeatedly hit by heavy shell, some of which, entering through the unprotected bottom must have penetrated to, or burst in or near her magazines.

(2) - A turret in "Seydlitz" was seen to be surrounded by sheets of flame rising as high as her masthead and obviously due to fire in the magazine.

(3) - "Koln" was under the concentrated fire of five Battle Cruisers at about 6000 yards for some minutes, but there was no trace of an explosion.

(4) - A light cruiser reduced to sinking condition passed the whole length of the battle line under heavy fire and burning furiously, but yet did not blow up.

These extracts bear out other evidence that the structure of the German ships was at least as severely damaged and penetrated by shell as those of the British Fleet; and it is to be observed that that it was publicly announced very shortly after the battle that the British ships were repaired and in fighting trim, whereas a similar announcement has only been made at the end of September for the German ships.

The Vice Admiral considers (par. 8) that -

(1) - either our methods of ship construction are seriously at fault; or

(2) - the nature of the ammunition we use is not sufficiently stable to ensure safety.

As regards (1) - the methods of ship construction adopted for warships are very little different in any navy, and for a new navy like that of the German it is doubtful if they have done any other than follow our practice as nearly as they can; and this has been practically admitted in debates in the Reichstag. Moreover, the method of constructing warships, although generally more intricate, follows the same lines as those adopted in the highest class of merchant shipping, in which Britain undoubtedly leads the world.

It is considered, that our losses must be put down to the cause stated in par. 1 of D.N.O's remarks. As the outcome of years of battle practice firing, it was the general and accepted opinion that a good supply of ammunition near the guns, also in ammunition passages &c., was most essential, and that the risk of cordite fires must be accepted - (See opinions expressed in G.15134/14) - and although after the engagement on the Coronel Coast and at the Falklands, this opinion was corrected by Gunnery Order G.043-15 dated Feb. 1st.1915 there is little doubt that accumulations did exist in turrets and gun batteries during the battle. That the charges in "Lion's" turret, hoists, and working space were not sent back into the magazine before the doors were closed is an indication of the manner in which loose cordite was regarded on our ships.

The Vice Admiral pointed to the fact that British Destroyers that have been sunk did not blow up, and apparently argues therefrom in favour of ammunition charges being in cases, but it should also be noted that British Light Cruisers ("Southampton" & "Chester" &c.,) have been under heavy fire without blowing up, and that these cruisers have B.L. guns, the difference between them and big ships being the absence of a mounting with a hoist extending down into the magazine.

The drawings of German gun mountings that have been examined show similar arrangements to the British, that is a trunk extending down to the Handing Room and Shell Room, but a sketch has been seen for "Thuringen" showing how the trunk of a broadside turret was not carried through the armoured deck, and it is possible that similar arrangements have been adopted in later ships. An N.I.D. pamphlet has been seen which contains a description of the system of supply to the German 30.5 c.m. guns which indicates that there are several breaks in the course of ammunition and that great care has been exercised to prevent a fire extending to the magazine.

As regards the points raised in par.10:-

(a) and (b) - Sketches are attached showing the positions of all magazines relatively to the L.W.L. and the deep W.L. in the following ships:-

"Indomitable" class.

"Indefatigable" "Australia" and "New Zealand"

"Lion" and "Princess Royal".

"Tiger".

"Queen Mary".

"Repulse" and "Renown".

"Courageous" and "Glorious".

"Furious",

and also the armour and deck protection provided for them.

As shewn in the drawings, the general endeavour in British practice has been to put the magazines at the centre of the ship. By this means they are protected from under-water and shell attack. Some drawings of German gun mountings have been examined, and these shew the magazines above the shell rooms, but there is a drawing published by the "Engineer" of the "Grosser Kurfurst" shewing the shell room above the magazines, but the latter are about 12-feet above the keel, thus bringing the crown of the shell room to L.W.L. so that the actual position of the magazine in the ship is not very different from that in British ships. A N.I.D. pamphlet giving information concerning the German 30.5 c.m. mounting states that the cartridge and the shell loading room is on the upper platform deck, magazines are on the lower platform deck, but it is not known whether this is based on reliable information.

Tudor minuted on 26 October:

This is a somewhat severe criticism of our ship construction, and I do not feel that it is justified – especially after reading DNC's report.

Immediate and far-reaching steps were taken directly after the action of 31st May, which have put the whole of our armoured ships on a much better footing; and practically all of the points mentioned by Admiral Beatty have received attention.

I propose to investigate further para (a), (b), (d), (e), (f), (h), & L of DNC, and steps should be taken forthwith.

There is very little doubt in my mind that in the great anxiety to attain a rapid rate of fire, the ordinary precautions for safety of cordite cartridges have been gradually relaxed, until at last the test of the enemy's shells has proved the danger of what was being done. -Stringent orders and precautionary and protective measures have now been taken to safeguard charges; and I feel confident that they will have the desired effect.

I do not agree that we should gain anything by the proposed committee (para. 9 of Vice-Admiral's letter). I feel greater confidence in the opinions of Naval Officers who know all the interests involved and are not slow to recommend any definite improvement, which it is their continual endeavour to suggest; and that these proposals should receive the careful consideration of the Admiralty, as is now the procedure.

It seems desirable that a reply should be carefully drafted embodying the gist of DNO's and DNC's remarks, and laying great stress on the undoubted improper exposure of cordite during this action.

Jackson noted beneath on 27 October:

Experiments with cordite in the magazines of some old ship are most desirable to ascertain the effect of burning charges & a programme should be prepared.

27/10/16

The sections italicised in Tudor's minute were highlighted in red pencil, and the bottom of the minute sheet has been signed in red by the First Lord, Arthur Balfour.

Graham Greene sent the Board's reply to Beatty on 4 November:

I have laid before the Lord Commissioners of the Admiralty your letter of the 14th July last No.240/B.C.F.05. in which you offered observations on the causes of explosion in British warships and suggested matter for investigation.

Their Lordships took immediate and far-reaching steps after the action of the 31st May to introduce improvements in the construction of armoured ships with the object of securing a greater measure of immunity from explosion, and They have caused much attention to be devoted to the majority of the points which you have placed before them.

Having given careful considerationto the reports and opinions available to Them, My Lords are forced to the conclusion that in some of the ships engaged in the action of the 31st May the precautions essential to the safety of cordite cartridges were to a certain extent subordinated to the great desire necessarily felt to achieve a rapid rate of fire. My Lords consider that the stringent instructions and measures, precautionary and protective, which have now been instituted will have the effect of safeguarding charges and sensibly diminishing the risk of explosion.

Your proposal for the establishment of a Committee of experts does not commend itself to Their Lordships. They have the utmost confidence in the opinions of the Naval Officers whose experience is able to from time to time to suggest expedients as a result of their practical knowledge of the issues at stake. It is the practice to devote to such suggestions the careful analysis of Their advisers, and they are disinclined to vary that procedure in the present case.

Of the points which in paragraph 10 of your letter under reply you particularly recommend six, viz: (a), (b), (d), (e), (f) and (h) are being subjected to special examination. Attention is also being given to the important question of introducing breaks in the course of ammunition in order to prevent fire from extending to a magazine. As regards item (c), the necessary steps have been taken to provide additional protection to roof plates, glacis, and trunks.

With reference to the proposal (g) that the permanent fixing of igniters to charges should be abolished, I am to state that trials have shown that igniters are very little more inflammable than cordite itself, and it is established that the discs now fitted afford more protection to the charge during its passage to the gun than would be the case if both igniter and disc were dispensed with.

The apparent immunity of German nitro-cellulose propellants as compared with cordite (i) is considered to be due rather to the protection of charges than to the nature of the propellant.

As to point (j) the ready communication of explosion from one magazine to another widely separated from it, My Lords propose to consider whether the introduction of gas checks in the trunk and working chamber is practicable.

The requisite action has been taken to deal with the subjects treated in sub-paragraphs (k) and (l).

The question raised at (m) viz:- the introduction of the Q.F. principle of British mechanism for all future guns depends for its solution partly at least on the conclusions which may be arrived at as a result of the investigation of the protection of charges (h).

A copy of this letter is being forwarded to the Commander-in-Chief.

In the meantime, on 16 November Tudor minuted:

Noted.

Action on all material points has been taken on other papers.

I am in full agreement with D.N.C. as to the cause of the explosions in our Battle and Armoured Cruisers. There is no evidence to show that any enemy shell penetrated to the magazines of our ships, on the contrary the immunity of engine and boiler rooms generally, points to exactly the opposite conclusion.

On the other hand there can be no doubt that the amount of exposed cordite about the ships was enormous and that as regards turrets, if bare charges were permitted to remain in the handing rooms, as there is every reason to believe was the case, these must have furnished trains of explosives to the magazines.

The very narrow escape of "LION" from blowing up affords an immediate explanation of the disasters which occurred to the other ships.

Even with the precautions which have been taken since the action, I do not feel that we are safe without more efficient control of the ammunition parties, who are, in most ships, I have little doubt, in isolated positions without Officers. This is due not only to the unavoidable stringency in Officers, but also because such an abnormal number are required for control of fire.

The question of Officering the ammunition supply parties is one which has caused me grave concern for over 25 years, but the difficulty seems to be almost insuperable.

One of the most unfortunate results of this Battle has possible [sic] been to give a false idea as to the necessity and value of armour protection; we should all like to have as much armour as possible, but for every ton we add some other feature of the design has to be sacrificed.

The "RENOWN" and "REPULSE" for example, for which such exertions and sacrifices have been made, will now be demobilised for many weeks and then speed and draught will never be what they were designed for.

FCTT 16/11/11

Sir Henry Jackson replied on 17 November:

The summary of information elicited from the perusal of these papers should be edited to remove any question of personal criticism, & prepared for issue to the Fleet as in the case of the T.B.Ds.

I feel sure the drawing prepared by DNC of the tracks of projectiles & the deductions drawn would be received with great interest.

HBJ

On the same day, Beatty replied to the Board's letter of 4 November:

Sir,

With reference to Admiralty Letter S.01146/16, dated 4th November, 1916, I would submit that as regards Their Lordships' conclusion, stated in Paragraph 3, there is no evidence that, in the ships lost, the "precautions essential to the safety of cordite charges" (so far as the Admiralty at that time had defined them) were neglected, neither is there any proof of irregularities in the then prescribed drill for cordite supply.

2. As regards clause (i), Paragraph 10 of my submission No.240/B.C.F.05 of 4th July, 1916, the big fires which actually occurred, without explosions, in "SEYDLITZ" and other ships still require explanation.

3. As to clause (j), Paragraph 10 of my above quoted submission, it does not appear that the introduction of the gaschecks referred to would remedy the possibility of sympathetic explosion in magazines widely separated.

4. Similarly the clauses (k) and (l) were intended to refer to the possibility of the sympathetic detonation of noze-fuzed H.E. shell, and it would appear to be desirable to ascertain by experiment that Lyddite shell will not explode, or detonate, as the effect of internal explosion, or violent lateral movement: i.e., as referred to in Paragraph 8 of my original letter, is our ammunition of a sufficiently stable character to ensure safety?

5. On this point any explanation of the blowing up of "AUDACIOUS", which still remains a mystery, would be of value.

6. It was for the purpose of elucidating these obscure points that I suggested that the greatest experts on high explosives should be consulted; they would, or should, be able to fix the cause of what is apparently a radical fault, and which certainly does not obtain in the ships of the enemy.

7. The opinions of Naval Officers, whose experience suggests expedients, only result in attempting to provide a cure, but leave the cause unknown.

In forwarding Beatty's letter, Jellicoe added his own observations:

Forwarded. I entirely concur with the Vice-Admiral Commanding, Battle-Cruiser Fleet, that there is no evidence that, in the ships lost, the precautions essential to the safety of cordite charges, as we knew them, were neglected.

The drill and custom then in force was to keep all cages and waiting positions loaded and the magazine doors open, and all the evidence seems to show that if a turret was pierced by a shell which exploded inside it, the magazine was almost certain to blow up. I therefore ask that their Lordships may reconsider the conclusion stated in paragraph 3 of their letter S.01146/16 of 4 November, 1916.

3. It is quite realised that absolute immunity from explosion cannot perhaps be expected in action in a ship carrying many hundreds of tons of explosives in a confined space, but it is considered that every possible means should be taken to investigate the causes that may lead to these explosions so that they may be overcome, if possible, and the method suggested by the Vice-Admiral Commanding, Battle-Cruiser Fleet, appears to be the one most likely to meet with success.

4. Fourteen German ships - battleships to light-cruisers, have been sunk by gunfire alone and none of them have blown up. Nine British ships - battleships to light-cruisers, have been sunk by gunfire, of which six blew up.

From a study of these figures it is difficult not to conclude that the Germans have the advantage over us in either fuzes, explosives, or ship construction.

In a minute of 19 December, D'Eyncourt claimed:

The point of particular interest noted from a perusal of the reports from the Commanding Officers of the Battle Cruisers, Cruisers, and Light Cruisers, engaged in the action of the 31st May 1916, is that the Battle Cruisers were in action against enemy Battle Cruisers and Battle-ships, and that the three ships, "Indefatigable", "Queen Mary" and "Invincible" that were lost, were blown up during the early part of the action when engaged with enemy Battle Cruisers. These three ships were sunk before they had received heavy punishment and the deduction is that the flame reached the turret magazines, causing them to explode.

It is now the generally accepted opinion that the fault to which these explosions may be attributed lay in the method adopted in the transportation of charges to the guns, whereby these charges which were not in non-inflammable cases had an open course from the magazine to the gun. This, in association with the number of charges that were usually in the Handing-Room, Revolving Trunk, Working Chamber, and Gun House provided a direct train of cordite from the turret to the magazine.

There would seem to be an impression in the Fleet that these three ships were lost because enemy shells penetrated the lower protective deck and exploded either in the magazine or so close to it as to ignite the contents. This is not substantiated by a detailed examination of all the reports that have been received, and in the ships that returned from the engagement there is no known case of an enemy shell travelling so far down before bursting and only one known case (that of "Barham") where a shell, which burst a short distance beyond the point of penetration, sent a fragment so far into the ship. Further, there were very few cases where fragments of projectiles penetrated the protective deck over the machinery spaces, which occupy a much larger portion of the ship than the magazines, are in the midship part of the ship, and are not better protected.

As this matter is of extreme importance the accompanying diagrams have been prepared which show, by means of vertical sections through the path of the shell, all the principal hits and bursts that have been traced in the Battle Cruisers, and Battle-ships engaged. It will be seen that these do not bear out the contention that enemy shells can penetrate the lower protective decks of modern Battle Cruisers, and Battle-ships, before they burst, not that they burst so far beyond the point of entry as to explode in the immediate vicinity of the magazines. If the impression that enemy shells can do this amount of damage be allowed to remain it will lead to demands for a further considerable increase in protection in future warship construction, and the result will be that ships will become very much greater in displacement and cost, without proportionate increase in armament, as a greater proportion of the total weight will be given up to protection than hitherto.

The fundamental maxim of British Warship design has been that the best defence is superior power of offence and it is considered that this action shows this maxim to be essentially sound, as although British Battle Cruisers were in action with enemy Battle-ships they were not then put out of action, whereas the more heavily protected and less heavily armed German ships received very severe punishment.

Tudor initialled his acknowledgement the following day.

The Fate of Rear-Admiral Tudor

There is a myth circulating the internet that the Third Sea Lord, Frederick Tudor, was exiled to the China Station as punishment for his part in this saga. This perhaps stems from a passage in Lambert's influential article on these proceedings, which reads:

Shortly thereafter Tudor was appointed out of the Admiralty. But instead of receiving an appointment to the Grand Fleet, as was his due, Tudor was sent to command the handful of dilapidated cruisers guarding British commercial interests in China.

This section of the article will expose the fallacy of that argument.

(a) One has to ask why Tudor was apparently singled out. The D.N.O., Singer, did go to the Grand Fleet, as Rear-Admiral in the Tenth Cruiser Squadron in April, 1917. His departure is explained by the shakeup of the Naval Ordnance Department in March, 1917, and Jellicoe's desire to have his own man, Captain Frederic C. Dreyer, on hand to deal with the shell problem revealed at Jutland. He was still a junior Rear-Admiral so a junior appointment in the Grand Fleet can't be seen as either favouritism or as exile.

The D.N.C., Tennyson D'Eyncourt, remained in his position for another seven years.

(b) Lambert's use of the words "Shortly thereafter" is misleading. Tudor was not relieved as Third Sea Lord until 1 June, 1916—five months thereafter. Quantifying periods of time is naturally subjective, but it's difficult to call nearly half a year "Shortly."

(c) The question of whether Tudor should have received a command in the Grand Fleet. The simple answer is no, and that Tudor should have been grateful to have been given a seagoing command at all. He had not been to sea in nearly seven years, and had not flown his flag in over four years as a Flag Officer. He was rapidly approaching the top of the Rear-Admirals' list in seniority, and under the provisions of the Order in Council of 9 March, 1914, if he had not hoisted his flag as a Rear-Admiral he would have been automatically placed on the Retired List on promotion to the rank of Vice-Admiral. Tudor was appointed Commander-in-Chief on the China Station on 20 July, 1917, and assumed command on 4 October. He was promoted Vice-Admiral on 23 October. Four and a half years without a seagoing appointment and three months until promotion to Vice-Admiral. Unless Tudor had received assurances about his future (which this writer is still searching for) he must have been worrying about his future.

(d) With regards to his relative unsuitability for an appointment in the Grand Fleet which Lambert thinks Tudor so richly deserved, it is perhaps having a cursory look at the recent service of the Rear-Admirals who were serving in the Fleet at the time Tudor was relieved as Third Sea Lord, 1 June, 1917:

* Technically Rear-Admiral Gaunt had gone afloat as Rear-Admiral in the First Battle Squadron on 25 August, 1915. His appointment as Rear-Admiral in the Fourth Battle Squadron was due to a post-Jutland reorganisation of the Grand Fleet Battle Squadrons.

Tudor's last spell of sea service had ended when he handed over command of H.M.S. Superb on 16 August, 1910. The only officer even approaching his six and a half years ashore was Rear-Admiral Morgan Singer, who as already noted was still a junior Rear-Admiral, and whose appointment in the Tenth Cruiser Squadron, whilst in the Grand Fleet, could hardly be considered a position of great importance.

The notion that Tudor, a senior Rear-Admiral with no recent experience of handling a ship, let alone ships, should be given a command befitting his rank in the Grand Fleet, is preposterous. Lambert might pooh-pooh the China Station as a "handful of dilapidated cruisers guarding British commercial interests in China" but it gave Tudor all-important service as a Flag Officer, which was necessary if he was to continue on the Active List, and it gave him the status of a Commander-in-Chief and made him senior officer in the Far East.
