Passage: The sailors and stokers were now pulling out all the stops to prevent the fleet setting sail again and to achieve the release of their comrades. Some 250 met in the evening of 1 November in the Union House in Kiel. Delegations sent to their officers requesting the mutineers' release were not heard. The sailors were now looking for closer ties to the unions, the USPD and the SPD. Then, the Union House was closed by police, leading to an even larger joint open air meeting on 2 November. Led by the sailor Karl Artelt, who worked in the torpedo workshop in Kiel-Friedrichsort, and by the mobilised shipyard worker Lothar Popp, both USPD members, the sailors called for a mass meeting the following day at the same place: the Großer Exerzierplatz (large drill ground).

Question: what request were deaf ears turned to?
mutineers' release
