The battle

U-210 brings up 5 other boats: U-164, U-217, U-511, U-553 en U-588. All their attacks on the 30th and 31st are repulsed by the escort. On the 31st U-588 is sunk by the Skeena and Wetaskiwin.

During the night of the 31st contact is lost. The two destroyers are short on fuel and depart for St-John's at Newfoundland. The 5 remaining boats form a patrol line together with the 7 replenished boats of the "Wolf"-pack.

On the 2nd Aug the escort is reinforced with the destroyers Hamilton and Witch (RN) and the corvette Galt. The Wetaskiwin is short on fuel after several pursuits and leaves the convoy. U-552 locates the convoy and vectors in the other boats.

The convoy commodore tries to escape with ordering sharp course changes, but the only result is that one column cannot follow the movement and romps away from the convoy. The U-boats focus on this group: U-552 torpedoes 2 ships and U-553 sinks one. U-607 finishes off one of the damaged ships. The other one is taken in tow by the Agassiz. Attacks by U-71, U-217, U-597 and again U-552 fail.

Next day on the 3rd, the operation is broken off because of the bad visibility.
