Ships of the Battle Fleet were detached to the northward, two or three at a time, during the operations, to carry out gunnery practices by day and by night. Thick fogs were prevalent during the whole period, and ships detached from the Fleet experienced very considerable difficulty in rejoining. The foggy weather nearly resulted in a serious collision between a battleship of the 6th Battle Squadron and one of the Dreadnought Battle Fleet, the two ships passing within a few feet of each other on opposite courses.
On the return of the Battle Fleet to Scapa on the morning of October 12th, Admiral Sir Stanley Colville reported that a partial submarine obstruction was in place across the Hoxa entrance. The presence of even a partial obstruction reduced the danger of submarine attack on the Fleet whilst coaling, a matter which had given me much anxiety since the beginning of hostilities.

WHILST CANADIAN CONVOY WAS CROSSING.
On arrival in harbour it was found that the condenser tubes of the Iron Duke were in a bad condition, although the ship was quite new, and that the condensers would need either complete, or partial, retubing. The discovery was very disconcerting when taken in conjunction with the case of the Orion, the condensers of which ship had been retubed during September; it naturally led to suspicion being directed to the condenser tubes generally of other ships, from which reports of cases of tubes occasionally giving out were being received.
The whole question was taken up with the Admiralty, requests being made that all available spare tubes should be sent at once to the Northern bases, together with some dockyard fitters who could assist the artificers of the Fleet in the work of retubing. Representations were also made as to the urgent necessity of increasing the stock of reserve tubes in case the defects became general in the Fleet owing to the ships being so constantly under steam at sea. The task of replacing the defective tubes in the Iron Duke’s condensers was begun at once, with the help of the artificers of the Fleet, and the Centurion was detailed as the spare Fleet-Flagship in case of emergency. But at this time the Iron Duke was not kept specially in harbour for retubing work, this being carried out as opportunity occurred, although under considerable difficulties, since the labour of suddenly preparing for sea, with a condenser undergoing retubing, was very appreciable. The manner in which this heavy work was taken in hand and rapidly completed in several ships, largely by Fleet labour, demonstrated the extreme efficiency and very fine spirit of the engine-room departments of the ships of the Grand Fleet.
From the 12th to the 16th October the 1st and 4th Battle Squadrons remained at Scapa, and at 6 P.M. on the 16th they left to carry out target practice to the westward of the Orkneys. The 2nd Battle Squadron left Scapa on the evening of the 13th to support the cruisers in the North Sea; it joined the 3rd Battle Squadron already there, the ships of which were being detached to Scapa two at a time to fuel and to overhaul their machinery. It was found necessary to give these ships, with reciprocating engines, five days off duty periodically in order to carry out necessary adjustments.
