One of Three Prince Class Armed Merchant Cruisers (AMC)
Prince Robert ~ Prince Henry ~ Prince David

These ships were former CPR small coastal liners. Originally very fast liners for Canadian National Steamships, these formerly 3-funnelled ships were acquired by the RCN at the beginning of the war for conversion to AMCs. In their initial role they were the most powerfully armed ships in the navy until the arrival of the light cruisers.

All three spent some time intercepting merchant traffic, and PRINCE DAVID and PRINCE ROBERT were put under US command for operations in the Aleutians. DAVID and HENRY were converted to Troop Landing Ships and served on D-Day and the invasion of Southern France, as well as additional service in the Mediterranean. Before her 1943 conversion, ROBERT spent her time looking for enemy merchant shipping. She was then converted to an AA ship, and escorted convoys in the Mediterranean as well as serving on the New Zealand station for part of the war. In July, 1945, she went to join the British Pacific Fleet, and in August arrived in Hong Kong to facilitate the release of the Canadian POWs and in order for her Captain to represent Canada at the surrender ceremonies. DAVID hit a mine off Greece ending her wartime service, HENRY (as a British ship) and ROBERT repatriated soldiers, and DAVID and ROBERT were sold back into mercantile service. ROBERT was then converted into a luxury Italian ocean liner and sailed under the name, S.S. LUCANIA.
