Early on the 30th, the crew of "Helgoland", which was directly behind "Thüringen" in the harbor, joined in the mutiny. The I Squadron commander sent boats to "Helgoland" and "Thüringen" to take off the ships' officers, who were allowed to leave unharmed. He then informed the rebellious crews that if they failed to stand down, both ships would be torpedoed. After two torpedo boats arrived on the scene, both ships surrendered; their crews were taken ashore and incarcerated. The rebellion then spread ashore; on 3 November, an estimated 20,000 sailors, dock workers, and civilians fought a battle in Kiel in an attempt to secure the release of the jailed mutineers. By 5 November, the red flag of the Socialists flew above every capital ship in Wilhelmshaven save . The following day, a sailors' council took control of the base, and a train carrying the mutineers from "Helgoland" and "Thüringen" was stopped in Cuxhaven, where the men escaped.
