After the first sighting, the groups Spitz and Ungestum are immediately deployed against the convoy. In the night U-356 makes 2 attacks and torpedoes 4 ships, of which 3 sink and the other one is finished off by U-441. U-441 misses the St-Laurent and the convoy. U-356 is sunk after her second attack by the St-Laurent, Napanee, Chilliwack and Battleford. Contact is lost but regained by U-225 in the afternoon of the 27th. The boat attacks during the night and damages one ship, Scottish Heather, that successfully made it back to Scotland. U-260 makes contact with the convoy in the morning of the 28th and brings up 12 boats : U-123, U-203, U-225, U-406, U-440, U-662 and U-664 from the Sptitz group and U-336, U-435, U-591, U-615 and U-628 from the Ungestum group. As soon as darkness falls, the boats attack, sometimes more than once. In 3 hrs time they sink 9 ships: First U-435 and U-203 miss, then U-591 torpedoes one ship that is finished of later in the day by U-435. U-225 sinks one and damages one, which U-662 finishes off. U-260 sinks one and U-203 misses again. U-406 torpedoes 3 ships of which none sinks immediately, but they are sunk by by U-123, U-628 and U-591. At midnight U-225 torpedoes two ships, one is later again torpedoed by U-336 but needs a third torpedo from U-225 again. U-225 takes the captain prisoner. The other ship (the ship of the convoy commodore) is also torpedoed twice, by U-123 first and then U-435, before finally sinking. Further attacks by U-203, U-435, U-628, U-664 and again U-628 against the escort and convoy fail. On daylight of the 30th the escort is reinforced by the 2 British destroyers Milne and Meteor. U-260, U-591 and U-435 are driven off. Only U-435 manages to sink ship previously damaged by U-591 in a daylight submerged attack. The auxiliary vessel Fidelity was attacked several times by U-225 and U-615 but the ships escapes thanks in part to her torpedo nets. U-435 finally sinks her in the afternoon of the 30th. U-455 keeps in touch with the convoy until night, but does not bring up any more boats to attack the convoy.
