The Coordinated Attack against Hungary

The Allied council demanded that Romania leave Tiszántúl and respect the new borders. Romania said it would only do so after the Hungarian Army demobilized. Kun said he would continue to depend on the might of his army. On 11 July, the Allied council ordered Marshal Ferdinand Foch to prepare a coordinated attack against Hungary using Serb, French and Romanian forces. Hungary, in turn, prepared for action along the Tisza River.
