HMCS Trentonian was a modified Flower-class corvette that served with the Royal Canadian Navy during the Second World War.

[3][4][5] The "corvette" designation was created by the French as a class of small warships; the Royal Navy borrowed the term for a period but discontinued its use in 1877.

The platform for the 4-inch main gun was raised to minimize the amount of spray over it and to provide a better field of fire.

It was also connected to the wheelhouse by a wide platform that was now the base for the Hedgehog anti-submarine mortar that this version was armed with.

[2] After working up, Trentonian was assigned to Western Approaches Command in March 1944 in preparation for duties in association with Operation Neptune, the naval component of the Allied invasion of Normandy.

[12][13] Two United States destroyers, Plunkett and Davis, picked up the cable ship and escort on radar.

Trentonian proceeded to Monarch rescuing men thrown overboard and treating wounded.

[2] In late August 1944 Trentonian transferred to Plymouth Command and was made part of escort group EG 41.
