Gunnery Report, H.M.S. Marlborough.

H.M.S. Marlborough, 4th June 1916.

GUNNERY REPORT

Number of Rounds fired.

Gun.	№ of Rds. fired.	A.P. Lyddite.	Common.
13·5 6-in.	162 60	138 Lyddite Comm. 55	24 5

Breakdowns, Accidents, &c.

(1) Right gun of "A" tuuret had inner "A" tube and jacket cracked, a large portion of jacket being broken off. This occurred about the 5th round fired by this gun, and it is considered that a premature must have occureed, although the damage to the rifling is comparatively small. A.P. lyddite was being fired.

(2) After the ship was struck by a mine or torpedo, it took up a list of about 7° to starboard. Due to this list, difficulty was experienced in all turrets due to shell slipping forward as it rolled out of main cage into waiting position and fouling driving band with shell brake. Four turrets had to unship brake.

(3) Due to heavy list, all firing generators in turrets flooded, and it was necessary to disconnect pipe and allow water to drain away.

Detailed record not kept.

Missfires.—Nil.

Control and method of fire.

Controlled from fore top; firing by director. No difficulty was experienced in distinguishing own shots or in spotting overs or shorts, and hits could easily be distinguished by a deep red flame and clouds of grey and white smoke; occasionally when shell burst well inside ship no flame could be seen, but only a large amount of greyish smoke.

Without the director, it would have been almost impossible to keep gunlayers on correct object; there was so much confusion amongst enemy's ships, one ship was passing another; smoke from cruisers on fire often obliterated the object; own ship was continually altering course small amount; the above made it difficult to keep on the same object for any length of time.

Description of firing.

With objects fired at. All times are Greenwich mean times. Only hits that were actually seen and confirmed by two or more persons are given.

Time
6.10 p.m.	Sighted British battle cruisers engaging enemy's ships.
6.12	Red 7, cruiser, four funnels, one mast (disappeared in smoke and mist before fire could be opened).
6.15	After deploying to port. Battleship, two funnels widely separated, two masts (probably Kaiser class) estimated range 10,000 yards, rangefinders could not get a range.
6.17	Opened fire. Seven salvoes were fired in 4 minutes; 5th and 7th were clearly seen to hit. In the 5th salvo a deep red flame could be seen and salvo struck, in the 7th salvo a large volume of grey smoke appeared.
6.21.	Ceased firing, as enemy was hidden by cruiser on fire (Roon class).
6.24.	Green 98, a cruiser, 3 funnels (Roon, one funnel gone) ? range by rangefinder 10,500 yards.
6.25.	Opened fire. 5 Salvoes were fired. Hits could not be distinguished for certain , as two or three ships were firing at same object.
6.27.	6-in. guns opened fire at same object. It was during this firing that right gun of "A" turret was severely damaged and put out of action, cause not known for certain, but probably due to premature. It was about the fifth round fired by the gun, A.P. Lyddite was used. Inner "A" tube is cracked all round about half way along gun. A large portion of jacket is broken off, and a crack extends 15 ft. along jacket.
6.29.	Checked fire. There was a pause of ten minutes, during which the ship was altering course, and enemy was hidden by smoke.
6.39.	Object a battleship of Kaiser class. Range 13,000 yards; one salvo was fired, and enemy turned away and disappeared.
6.42 to 6.54.	Ship was altering course, and enemy's movements were very difficult to follow.
6.54.	Marlborough was hit by a torpedo or mine in Diesel engine room. The shock was sufficient to shake off switches on lever power board, and some fuses in telephone circuits. These were very quickly replaced, and all control instruments were found to be in step.
7.0.	Passed destroyer Acasta on port hand flying 6 flag and with collision mat over starboard quarter. Green 90 a cruiser of Roon class, stopped, range by rangefinder 9,800 yards.
7.3.	Opened fire. Fired four salvoes in two minutes, the 3rd and 4th both hit and appeared to open up her side, as a deep red flame could be seen inside her hull.
7.5.	Ceased fire, as she appeared completely disabled and sinking fast.
7.6.	Object shifted, a battleship two funnels widely separated, left hand ship of three (Markgraf class). Range by R.F. 10,750.
7.12.	Opened fire. Fired 14 salvoes in 6 mins., the 6th, 12th, 13th and 14th were all distinct hits. In the 6th salvo, a large cloud of grey and white smoke appeared near the foremast. In the 12th salvo two hits could be clearly seen under bridge and rather low.
7.18.	Checked fire.
7.19.	Enemy hauled out of line and turned away, lost in smoke; object shifted, one ship to the left that was not fired at.
7.20.	Enemy destroyer attack took place between the lines.
7.22.	6-in. guns opened fire. Turrets fired one salvo into the brown. After this, no more was seen of the enemy. During the night a lot of firing could be heard astern.

At about 4.0 a.m. a lot of firing could be heard to the southward, and shortly after a Zeppelin was sighted crossing the astern and steering approxiamtely east. Three-in. H.A. gun open fire and fired 12 rounds. "X" and "Y" turrets opened fire with A.P. shell, which was already in the guns, and two rounds of common which was in G.L. cage. Four rounds were fired. The nose of the Zeppelin was observed to dip very suddenly at one period, but it could not be ascertained for certain whether she was hit. Range varied between 5,000 and 10,000 yards.

If ship had not been disabled, rendering it undesirable to "A" and "B" turrets, it would have been worth while turning so as to get full broadside bearing.

G.C.C. ROYLE,

Lieutenant-Commander.

Damage Sustained

The principle damage, two views of which are given, was caused by the explosion of a torpedo which struck the ship on the Starboard side about 20 feet below the Water Line in the vicinity of 86 - 88 Stations.

The Outer Bottom Plating was holed irregularly from the lower edge of the armour belt to the outside edge of the Docking-Keel plate transversely, and from about 85 to 98 Stations longitudinally, an area of about 20 feet × 26 feet in extent. Beyond this the plating was distorted and indented generally to about 78 Station on the Forward side and 111 Station on the Aft side, and towards the Middle Line to between the 1st and 2nd Longitudinals.

The Inner Bottom Plating was holed to an extent similar to that of the Outer Bottom, and damaged over an area corresponding to that of the damaged Outer Bottom, which was also pierced in several other places adjacent by the lower ends of the stiffening angles on the transverse framing being forced through it.

The framing, both transverse and longitudinal, was torn and much distorted where the plating was holed, and very badly crushed over the remaining damaged area.

The Bilge-keel was completely carried away between 85 and 110 stations, a portion of the wood filling being found in a beam space under the Lower Deck against the Magazine Protective Bulkhead in the Dynamo Room. Between 78 and 85 Stations the Bilge-keel was distorted and torn away from the connecting angles which were forced inboard with the Outer Bottom Plating. At the After end of the damaged area, the upper part of the Bilge-keel was doubled back.

The outher edge of the slope of the Middle Deck between 80 and 111 stations was drawn downwards and inboard as was also the covering plate, the fastenings of the latter being carried away from the armour plate, but remaining intact in the outer bottom plating.

The bulkhead between the Wing Space and the Dynamo-room was penetrated and bulged in from the Inner Deck to the Inner Bottom. The inner Coal Bunker bulkhead was bulged in to a corresponding extent and also the bulkhead to the Forward Boiler Room, this limiting the extent of the damage in an inboard direction, although the watertight doors on the bulkhead were rendered non-watertight by distortion. The bulging of this bulkhead jammed the telegraph shafting running adjacent to it, and communication had to be made by other means.

The crown of the Dynamo Room which formed the floor of the Hydraulic Machinery Room and the floor of the Electric Lead Passage were bulged upwards, also the floor of the Dynamo Room, the Oil Drain Tank beneath it being badly damaged. The Hydraulic Tank was also damaged considerably.

The transverse bulkhead at 78 Station was damaged at its outer edge, where the fastenings were carried away over a small area. That at 90 Station was much distorted over an area extending from the Outer Bottom to the inner bulkhead of the Dynamo Room, a distance of about 20 feet. The bulkhead at 92 Station forming the after boundary of the Transverse Coal Bunker was also badly buckled from the Inner Coal Bunker Bulkhead to about 6 or 8 feet from the Middle Line. The Coal Bunker Bulkhead at 100 Station was buckled over practically the whole of its area, while the damage to 111 transverse bulkhead was limited to slight buckling at its outer edge where connected to the Inner Bottom.

The flats of the compartments between 66 and 78 Stations below the Middle Deck were strained causing leaks.

The torpedo-net shelf above the position of the damage was forced up by the explosion, three supporting brackets being torn away from the armour. The Upper Deck stringer-plate was also sel [?] up in the vicinity and fractured transversely for a short length.

Difficulty was experienced in opening the Conning Tower door after the explosion and it was found that the lower hinge pin was slightly bent.

The belt armour was neither damaged nor displaced by the explosion.
