Badge In front of a maple leaf an elephant’s head affronte
Motto Ad vigilamus undis (We watch the waves)
Authority King George VI, October 1943
The elephant head represents the squadron’s operations from Ceylon,
while the motto suggests its functions.
Formed at Stranraer, Scotland on 1 July 1941 as the RCAF’s eleventh –
third coastal and first flying boat General Reconnaissance – squadron formed overseas, the unit flew Catalina aircraft on north Atlantic reconnaissance and anti- submarine patrols. In March 1942, it was hurried­ly moved to the Far East. As aircraft and crews arrived at Koggala, Ceylon, they were pressed into service making reconnaissance flights over the Indian Ocean to watch for the approach of a Japanese naval force. On 4 April, S/L L.J. Birchall, whose aircraft and crew had arrived in Ceylon only two days earlier, sighted and reported a large Japanese fleet 350 miles south of Ceylon. The Catalina (Mk.I AJ155 “A”) was shot down by Japanese carrier air­craft, and S/L Birchall and the survivors of his crew were taken prisoner, but their warning had alerted Ceylon’s defences and the Japanese attack was repulsed. 1 The squadron remained in Ceylon until early 1945, 2 was then returned to the United Kingdom for conversion to a Bomber unit, but was instead disbanded at Bournemouth, Hampshire on 23 February 1945.
