The second attack took place on 6 July. A flight of twelve Fairey Swordfish torpedo bombers, armed with torpedoes modified for use in shallow water, were launched from the carrier in three waves of six, three, and three aircraft. They received an escort of three Blackburn Skua fighters. The French had failed to erect torpedo nets around the ship, and Gensoul, who had hoped to reinforce the idea that the ship had been evacuated, ordered that her anti-aircraft guns not be manned. Three patrol boats were moored alongside to evacuate the remaining crew aboard in the event of another attack, and these vessels were loaded with depth charges. The first wave scored a hit on the patrol boat "Terre-Neuve", and though it failed to explode, the hole it punched in her hull caused her to sink in the shallow water. Another torpedo hit the wreck in the second wave and exploded, leading to a secondary explosion of fourteen of her depth charges, which was the equivalent of of TNT, equal to eight Swordfish torpedoes. The explosion caused extensive damage to "Dunkerque"s bow and likely would have resulted in a magazine detonation had her captain not ordered the magazines be flooded as soon as the Swordfishes appeared. The blast killed another 30, bringing the total killed in both attacks to 210.
