By Friday 10 January 1919, it had become clear to most of those involved that the demonstrations, strikes and armed struggle known as the ‘Spartacist Rising’, against the Ebert-Scheidemann was failing. The government had gained the upper hand in Berlin, the ‘Vorwarts’ building was re-taken and a front-page announced the success of the government ‘Offensive Against Spartacus’.
The ‘Freikorps’, under the command of Defence Minister Gustav Noske, were beating the armed revolutionaries back and re-taking the city. Meanwhile, the ‘Revolutionary Committee’ of the Communists, Independent Socialists and Revolutionary Shop Stewards was disintegrating. That evening, the Communist leadership announced that they were ending all joint actions with the Shop Stewards, and effectively withdrew from the struggle. On the ground though, fierce fighting between armed workers and government forces continued.
