"During the night of 14–15 October [1917], the Pripyat assisted by three motorboats laid a field of mines in Kassar Wick north of Cape Pawasterort. According to one account, the Pripyat's mutinous crew had been replaced by more reliable men drawn from the destroyers and torpedo boats. When the German flotillas returned to the inlet the next day, the destroyer B.98 had her bow blown off and had to be towed back to Libau. The destroyer B.112, in seeking a path around the new minefield, grounded and was put out of action. Nevertheless, the heavy fighting in the waters around the north of Ösel was really over."
In the spring of 1917, German forces on the Russian front waited to see what would come of the Russian Revolution, and whether Russia wound continue to fight. The July Kerensky Offensive provided one answer, and the collapse of the Russian army in its aftermath a fuller one. German forces advanced in late summer, taking the Russian Baltic Sea port of Riga on September 3. The German fleet simultaneously advanced, threatening to enter the Gulf of Finland leading to Petrograd. The island of Ösel is, in 2017, Saaremaa, Estonia.
