Passage: By the end of August Posen and the rest of the High Seas Fleet had returned to their anchorages in the North Sea. The next operation conducted was a sweep into the North Sea on 11–12 September, though it ended without any action. Another fleet sortie followed on 23–24 October without encountering any British forces. On 4 March 1916, Posen, Nassau, Westfalen, and Von der Tann steamed out to the Amrumbank to receive the auxiliary cruiser Möwe, which was returning from a raiding mission.Another uneventful advance into the North Sea took place on 21–22 April. A bombardment mission followed two days later; Posen joined the battleship support for Hipper's battlecruisers while they attacked Yarmouth and Lowestoft on 24–25 April. During this operation, the battlecruiser Seydlitz was damaged by a British mine and had to return to port prematurely. Due to the poor visibility, the operation was soon called off, leaving the British fleet no time to intercept the raiders.

Question: When did the cruiser Mowe return?
4 March 1916
