HMCS Assiniboine and U-210
It is the kind of battle that Hollywood might dream up as fantasy, but it was absolutely real.
In August 1942 Canadian River class destroyer HMCS Assiniboine was escorting a convoy of 33 supply ships from Sydney Nova Scotia to the United Kingdom.
It was a terrible trip with fully 11 of the 33 sunk by U-boats.
On August 5, the destroyer and two corvettes were sent back to find and escort six stragglers now several miles behind the main convoy.
Alas the pack of U-boats had already found the SS Spar and from a distance, the destroyer could see the plume of smoke from the sinking ship. The corvettes drove off U-595 and U-593 and the warships began their search for the attackers
It was the next morning, a foggy August 6 that Assinboine again drove off U-595, but then U-210 was spotted in the fog less than 100 metres away, but it turned into the fog and was lost, apparently however not noticing the destroyer.
The ship then continued to search and in the fog again spotted the sub silhouette at about 1,000 metres and raced toward it. The sub and destroyer both opened fire at close range and as the sub began desperate evasive moanouevres, the destroyer churned the water in an effort to keep it in sight.
The destroyer was often too close to depress its main guns. However a shot did hit the conning tower killing the Captain and two others. Machine gun fire from the ship kept the U-boat crew from their deadly 88 deck gun, but not from the 20mm AA gun. Shots from the sub started a fire on the destroyer and damaged several other portions of the ship.
Several times the Canadian ship tried to ram the Uboat as the two twisted and turned around the ocean. The Canadian did ram the U-210 once, and then once again later, while another 4.7 inch shell finally penetrated the bow of the sub which began sinking.
Some 38 crew of the U-210 were rescued.
The 30 minute blazing desperate battle had destroyed the U-boat but left Assiniboine too damaged to continue, so it limped back to St. John’s for repair.
In spite of the intense onboard fire, and U-boat shells which had penetrated the Assiniboine in several places and caused much interior damage, only one Canadian had been killed and was buried at sea with full honours.
