to port after recovering the survivors. T11 remained in France until December when she began a lengthy refit in Germany. All of her sisters began their own refits between January and March 1941. After completing their refits, T2, T5, T8 and T11 supported German forces invading the Estonian islands (Operation Beowulf) in mid-September and then, reinforced by T7, they escorted the battleship , as it sortied into the Sea of Åland on 23–29 September to forestall any attempt by the Soviet Red Banner Baltic Fleet to breakout from the Gulf of Finland. T1, T8, T9 and T10 were reduced to reserve at some point during the year to alleviate manpower shortages. In November, T4, T7 and T12 successfully escorted the commerce raider Komet through the Channel and into the Atlantic despite an attack by British motor torpedo boats (MTBs). The following month T2, T4, T7, T12 and the torpedo boat successfully did the same for the commerce raider Thor although the British failed to react. On the morning of 12 February 1942, the 2nd Torpedo Boat Flotilla (with T2, T4, T5, T11 and T12) rendezvoused with the battleships and and the heavy cruiser to help escort them through the Channel to Germany in the Channel Dash. After their arrival, T4, T5, T11 and T12 were transferred to Norway for escort duties and were joined by T7 in April while T2 was reduced to reserve, followed by T11. T1 and T8 were reactivated and assigned to the Torpedo School as training ships in mid-1942. T4 returned to France in June, followed shortly afterwards by T10, and were assigned to 3rd Torpedo Boat Flotilla. The flotilla made an unsuccessful attempt to escort Komet through the Channel in October. They were intercepted by a British force of five escort destroyers and eight MTBs that sank the raider and severely damaged T10 which subsequently returned home and was paid off into reserve. T7 was briefly put in reserve in October before being assigned to the Torpedo School in January 1943. T4 and T10 returned to Germany in January and then joined T1, T7, T8 and T11 in the Torpedo School. T2 was activated and joined T9 and T12 in France in March 1943 while T5 arrived there that same month. T2, T9 and T12, all assigned to the 2nd Torpedo Boat Flotilla, were some of the escorts in late March for the Italian blockade
