Shortly after midnight on the night of 5–6 April 1945, the Georgians rose up and gained control of nearly the entire island. Approximately two hundred German soldiers were killed in the initial uprising, in their quarters or while standing guard, walking the roads of the island in groups or individually that night and the following day. Members of the Dutch resistance participated and assisted the Georgians. However, the rebellion hinged on an expected Allied landing which did not occur. Furthermore, the Georgians failed to secure the naval batteries on the southern and northern coasts of the island; the crews of these artillery installations were the only Germans still alive on the island.
