St George’s Channel: Royal Navy
PC.62 rams and sinks
U-84. The vessel responsible is sometimes listed as a United States patrol craft, but as far as I can tell, no US vessel was issued this hull number. There was, in fact, an HMS
PC.62 . The US did use the PC-designation, but as a follow-on to the earlier SC, so any 62 hull numbers should have been under that category (there was in fact, an USS
SC-62). HMS
PC.62 however, was a modification of the British P-class patrol sloops, the PC-class sloops being those P-class that were modified as Q-ships.
