HMS Grenadier (Pennant number: T334) was a Military class trawler of the British Royal Navy, which served as an Anti Submarine Warfare Vessel during the Second World War.

The skipper of Grenadier at the time was A/SkrLt Arthur George Day of the Royal Navy Reserve.

A/SkrLt Day realised that the men of Inger Toft whose vessel had now fallen beneath the water would have little chance of survival if they followed this routine.

For his actions A/SkrLt Arthur George Day was mentioned in dispatches, he received an oak leaf to be worn on his 1939-1945 war medal.

Following the war he returned to his pre-war occupation as a skipper operating from the small fishing port of Milford Haven, Pembrokeshire Wales.
