Passage: The convention disagreed with Ebert only on the issue of control of the army. The convention was demanding a say for the Central Council that it would elect, in the supreme command of the army, the free election of officers and the disciplinary powers for the Soldiers' Councils. That would have been contrary to the agreement between Ebert and General Groener. They both spared no effort to undo this decision. The Supreme Command (which in the meantime had moved from Spa to Kassel), began to raise loyal volunteer corps (the Freikorps) against the supposed Bolshevik menace. Unlike the revolutionary soldiers of November, these troops were monarchist-minded officers and men who feared the return into civil life.

Question: Which general entered into an agreement with Ebert?
Groener
