At 12.30 P.M. the 4th Battle Squadron was crossing under the stern of the remainder of the Battle Fleet and signals were being made to Vice-Admiral Sir Doveton Sturdee to steer clear of the position in which the submarine was sighted, but before any movement was effected the officer of the watch, Lieutenant-Commander Piercy, of the _Dreadnought_ of that Squadron, sighted a periscope close to, one point on the port bow, the submarine apparently steering a southerly course and zigzagging. Captain Alderson, commanding the _Dreadnought_, at once altered course direct for the submarine, increased speed, followed, and rammed her. The bow of the submarine came out of the water and her number, U 29, was plainly visible. She sank immediately. The _Blanche_, which passed close to the spot, reported a large quantity of wreckage, one article of clothing and much oil and bubbles on the surface, but no survivors. It seems probable that the captain of the submarine, after firing at the 1st Battle Squadron, was confused by the movements of the 4th Battle Squadron crossing astern of the remainder of the zigzagging Fleet, at high speed, and in trying to get clear failed to observe the _Dreadnought_ until too late. The _Dreadnought_ was admirably handled. On arrival of the Fleet in harbour I wired to the Admiralty urging that the fate of U 29 should be kept secret. The secrecy regarding the loss of this submarine, commanded by Commander Weddingen, was much resented in Germany, and many accusations of treacherous conduct levelled at the British, probably in the hope that we might give information as to her fate. The policy of secrecy was certainly correct, as it left the enemy entirely ignorant of our methods, and possibly had some effect of the moral of the submarine crews. The Fleet steered to the eastward until well clear of the area in case other submarines were present, and then shaped course for the bases, arriving on the 19th. On March 29th the Grand Fleet left its bases with the intention of carrying out a sweep of the North Sea, but the plan was abandoned and the Fleet returned to its bases on the following day. The principal movements of destroyers during March, additional to the regular patrols and fleet movements, were as follows: From March 2nd to March 5th search was made by a half flotilla for a number of oil drums reported as moored in certain areas in the North Sea. The report indicated that the enemy might be refuelling submarines in this manner; the search disposed of the supposition.
