5.	The M.A.C. ships, which had flight decks 400-460 feet long, must not be confused with the C.A.M. ships (Catapult Aircraft Merchantment, see Vol. I, p. 477) which were fitted with a catapult and carried only one single-seater fighter. Both classes sailed under the Red Ensign, and were stop-gaps introduced because of the urgent need to mitigate our lack of escort aircraft carriers.

18.	The fitting of metric radar sets in the Navy's larger ships for gunnery purposes and in its smaller ships for tactical and search purposes had started in 1940. Reconnaissance aircraft had also been supplied with sets of this type. Certain technical developments made in 1941 enabled a centimetric set to be designed. This needed a smaller and lighter aerial than any earlier set, and was able to pick up much smaller objects, and to show them on a new type of screen. It was eminently suitable for aircraft and coastal force vessels, and had many other uses as well.

A member of the Anti-Submarine Warfare Division of the Naval Staff produced the following doggerel at this time:     'Gaily the backroom boys,     Peddling their gruesome toys,     Come in and make a noise,     Oozing with science!     Humbly their aid we've sought;          Without them we're as nought,     For modern wars are fought     By such alliance'.

30.	The Queen Mary by Leonora Speyer. These lines were given to the author of this history by the American poetess shortly before he left New York for the Clyde in the Queen Mary in January 1944, to return to Britain with the ship's company of a damaged cruiser, and about 15,000 American troops. They were printed later in the New York Times.

34.	The stopping of convoys before operation TORCH and their subsequent restarting (sometimes under different titles) took place as follows: (a) OG 89 which sailed from Britain on 31st August 1942, was the last of the series before TORCH. OG 90, which sailed on 19th May 1943 was also called KX 10. The KX/XK series of 'special slow' convoys between Gibraltar and the United Kingdom had started on 2nd October 1942. (b) HG 89 left Gibraltar on 17th September 1942, and was the last of its series. Homeward-bound ships from Gibraltar were thereafter included in the MKS (North Africa-United Kingdom) convoys. (c) OS 42, which sailed from Britain on 29th September 1942 was the last before TORCH. OS-43 sailed on 14th February 1943. (d) SL 125 which, as told above lost thirteen ships, sailed from Freetown on 16th October 1942 was the last before TORCH. SL 126 sailed on 12th March 1943. See also Tables 24 and 25 (pp. 316-317 and 319).
35.	The average monthly number of merchant ships sailed on the South Atlantic routes at this time was as follows: Freetown to Cape of Good Hope 77 Cape of Good Hope to Freetown 30 Freetown to South America 27 South America to Freetown 40 U.S.A. to Cape of Good Hope 27 Cape of Good Hope to U.S.A. 57 U.S.A. to South America 36 South America to U.S.A. 17 Cape of Good Hope to South America 25 South America to Cape of Good Hope 16 TOTAL 352 ships

37.	This was the ex-French ship Le Rhin which, under Lieutenant de Vaisseau C. A. M. Peri, escaped from Marseilles at the time of the fall of France. She was later commissioned, still under her Free French commander, in the Western Approaches command, and performed many varied services in home waters and the Mediterranean before she was sunk.
