Attacks on U-99 during this patrol

In diving to escape an attack by a German aircraft which dropped three bombs, the boat suffered minor damage on striking the seabed. It continued the patrol after repairing the damage while settled on the bottom. (Sources: Ritschel)

7 Jul 1940
At 14.14 hours the boat tried to stop the armed merchant Manistee with gunfire after missing her with a G7e torpedo at 14.01 hours. No hits were scored in the gun duel, but the Germans broke off the attack when shots fell within 100-200m (109-118 yds) of U-99. (Sources: Ritschel)

After a successful attack on convoy HX 53 south of Fastnet, escorts dropped a total of 107 depth charges over 14 hours, but the boat escaped unscathed. (Sources: Ritschel)
