On 5 and 6 March, 1944, while part of the escort of the 63 ships of Convoy HX-280 from New York and Halifax to Liverpool HMCS CHILLIWACK, whose mast is on STAR’s quarterdeck, took part in a thirty-two hour attack on U-744, which finally resulted in her capture about 440 nm west of Ireland. Men from CHILLIWACK boarded U-744 and recovered code materials but much was lost when their whaler capsized. U-744 had to be sunk as unseaworthy.
CHILLIWACK already had one U-boat to its credit; U-356 on December 27, 1942.
