Devilmaster - a google search for HMS Hunter AND Trafalgar got no results. Interesting find: A midshipman serving on this ship grew famous later on: William Bligh of the Bounty.
Could it be that your old unit HMCS Hunter holds the battle honours of the old HMS Hunter who fought the Americans on the Lake Erie in 1812?
I have been doing some research myself. A google search on "ships at trafalgar" gave a couple websites and Hunter was not part of those lists. Odds are I was mistaken in that. To the other point, HMCS Hunter holds about a dozen battle honours, dating back to the 1600s. The last battle honours Hunter holds, matches the WW2 ship, HMS Hunter, Attacker Class assault carrier which garnered honours at Atlantic 1939 - 44, Salerno 1943, South France 1944, Aegean 1944, Burma 1945, Malaya 1945.
Naturally, now i'm more intrigued, and i'll probably head on down to the unit today to get the full list.
