4 Sep 1941
On 4 September 1941 a British bomber signalled the American destroyer USS Greer that a U-boat was in the vicinity. Greer picked up a sonar contact at close range and started to track the boat. The aircraft dropped four depth charges and then left the scene. Shortly afterwards U-652 fired a torpedo at the US warship, perhaps believing she was responsible. Greer then went on the attack, and a two hour battle followed, during which she dropped 19 depth charges and the U-boat fired another torpedo - no damage to either side. President Roosevelt used this event in his campaign to convince the US to go to war against Germany, and the "undeclared war" between U-boats and US escorts escalated dramatically from this point.

11 Dec 1941
At 1439 hours (Berlin time), while west of Ustica Island in position 38.42N, 12.51E, the Dutch submarine HrMs O 24 (Lt.Cdr. O. de Booy, RNN) fired three torpedoes at a German U-boat. A full bow salvo of four torpedoes was intended but the enemy changes course after the third torpedo had been fired which then all missed. The fourth bow torpedo was not fired. According to the German log U-652 spotted the periscope of the attacker and course was changed. Shortly afterwards two torpedo tracks were sighted.

2 recorded attacks on this boat.
