After unrelenting political pressure from Adolf Hitler, Yugoslavia signed the Tripartite Pact on 25 March 1941. On 27 March, a military coup d'état overthrew the government that had signed the pact, and a new government was formed under the commander of the VVKJ, "Armijski đeneral" Dušan Simović. A general mobilisation was not initiated by the new government until 3 April 1941 not to provoke Germany any further and thus precipitating war. However, on the same day as the coup, Hitler issued Führer Directive 25 that called for Yugoslavia to be treated as a hostile state; on 3 April, Führer Directive 26 was issued, detailing the plan of attack and command structure for the German-led Axis invasion, which was to commence on 6 April.
