Two surface actions take place in the English Channel involving Canadian destroyers. On April 26th, British cruiser Black Prince with four destroyers - three from the Royal Canadian Navy - is on patrol in the Western Channel. Early that morning they run into German torpedo boats T-24, T-27 and T-29 on a minelaying mission. T-27 is damaged and T-29 sunk by the Canadian 'Tribal' class Haida. On April 29th HMCS Haida and her sister ship Athabaskan are covering Allied minelaying operations, when they are surprised by the surviving T-24 and repaired T-27. After a short, sharp gun battle, Athabaskan is hit by torpedoes from the German torpedo boats. The ship's magazine and boiler blow up in an explosion that was seen 20 miles away. 129 of the crew went down with the ship. 83 men were picked up from the water by the torpedo boats and taken prisoner. Haida managed to drive T-27 ashore where she is later destroyed.
