Editing German submarine U-552 (section)

===Third patrol===
''U-552'' left St Nazaire for her third war patrol on 25 May 1941. In 39 days, she travelled into the North Atlantic and sank three British vessels: the ''Ainderby'' on 10 June, the ''Chinese Prince'' on 12 June, and the ''Norfolk'' on 18 June. During the attack on the ''Norfolk'', ''U-552'' attempted to attack the remaining ships in the convoy, but was forced to break off the attack due to the arrival of several of the convoy's escorts. All of these attacks occurred off the northwest coast of Ireland, and once ''U-552'' returned to St. Nazaire on 2 July 1941, she had amassed a total of 24,401 GRT from the ships she had sunk.<ref name=Patrol3>{{cite web
