The matter is one of which I have considerable personal knowledge, since it came within my province as Controller in 1909–11 and was also given to me to examine whilst Second Sea Lord in 1913. It is needless to say that on both occasions the necessities were pointed out with emphasis. These remarks are not out of place, as will be shown, as an introduction in a consideration of the Battle of Jutland, if that action is to be rightly judged. In following the proceedings of the Fleet it is essential to bear in mind that the time of receipt of signals, especially of reports emanating from the bridge of a ship, is not a true indication of the time at which the officer making the report began his task. A varying but considerable interval is bound to elapse; this includes the time taken to write out the report, transmit it to the wireless office or signal bridge, code it, signal it, decode it on board the receiving ship, write it out and transmit it to the bridge. The interval is greater with wireless than with visual signals. I.--THE BATTLE CRUISER FLEET’S ACTION The Grand Fleet put to sea on May 30th for the purpose of carrying out one of its periodical sweeps in the North Sea. The orders from me under which the Fleet acted were as follows: Vice-Admiral Sir Martyn Jerram, with the 2nd Battle Squadron from Cromarty, was directed to pass through a position in Lat. 58.15 N., Long. 2.0 E., and to meet the remainder of the Battle Fleet at 2 P.M. on the 31st at position (A) in Lat. 57.45 N., Long. 4.15 E. Vice-Admiral Sir David Beatty, with the Battle Cruiser Fleet and the 5th Battle Squadron, was directed to proceed to a position in Lat. 56.40 N., Long. 5 E., economising fuel in the destroyers as much as possible; it was expected that he would be in that position by about 2 P.M. on the 31st, after which he was directed to stand to the northward to get into visual touch with the Battle Fleet. [Illustration: Operations of BATTLE CRUISER FLEET II·00 p.m to VI·15 p.m. 31^{st}. May.] The _Iron Duke_ and the 1st and 4th Battle Squadrons, together with the 3rd Battle Cruiser Squadron, and the newly commissioned light cruisers _Chester_ and _Canterbury_, which had been carrying out gunnery and torpedo practices at Scapa, left that base during the evening of May 30th, and proceeded towards position (A), Lat. 57.45 N., Long. 4.15 E., having met the 2nd Battle Squadron _en route_ at 11.15 A.M. in Lat. 58.13 N., Long. 2.42 E. Sir David Beatty had been informed before sailing that the Battle Fleet would steer towards the Horn Reef from the position in Lat. 57.45 N., Long. 4.15 E.
