By the end of August, "Rheinland" and the rest of the High Seas Fleet units were back in their bases on 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 sortie followed on 23–24 October during which the German fleet did not encounter any British forces. On 12 February 1916, "Rheinland" was sent to the dockyard for an extensive overhaul, which lasted until 19 April. "Rheinland" was back with the fleet in time to participate in another advance into the North Sea on 21–22 April. Another bombardment mission followed two days later; "Rheinland" was part of the battleship support for the I Scouting Group battlecruisers that 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. Visibility was poor, so the operation was quickly called off before the British fleet could intervene.
