“[the Channel Fleet] no longer exists. The Atlantic and Channel Fleets were merged in 1912 by Winston Churchill as First Lord of the Admiralty to form the First Fleet, of four battle squadrons in full commission” (i.e. 32 battleships, in the proper sense of armoured capital ships, the strongest units of the fleet). “After the war” (World War I) “the main fleet at home was the Atlantic Fleet, until its name was altered to Home Fleet in 1932 (supposedly to help wipe out the memory of the Invergordon Mutiny – which many think was a shameful example of responsibility and odium being transferred from where it belonged to the unlucky men on the spot).”It is of interest, though perhaps not relevant here, that Admiral Brock still felt so strongly about the aftermath of the affair as to let his feelings as a naval officer show in a strictly literary context. The Invergordon Mutiny was a prime example of Government mishandling of a sensitive issue, without understanding the likely consequences. In the aftermath, scapegoats were found, and ‘spin’ employed to blur the issues. [A.W.]
“In 1922, the distance apart of ships in column in close order was laid down as 1½ cables (300 yards) for destroyers and below, 2½ cables (500 yards) for cruisers and battleships, and 3½ cables (700 yards) for battle-cruisers, but I believe it has been varied, before and since”. Today, it is 500 yards for ships less than 450 feet in length, and 1,000 yards for anything bigger.[lines 3 & 4] When her siren’s frightened whine / Shows her sheering out of line One short blast on the siren means “I am directing my course to starboard”: two blasts, to port. So, one short blast, out of the regular sequence of long blasts, means, in effect, “Follow me round to starboard”.
