After unrelenting 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 VVKJ commander, "Armijski đeneral" Dušan Simović. A general mobilisation was not called by the new government until 3 April, out of fear of offending Hitler and thus precipitating war. On the same day as the coup, Hitler issued Führer Directive 25 which called for Yugoslavia to be treated as a hostile state, and on 3 April, Führer Directive 26 was issued, detailing the plan of attack and command structure for the invasion, which was to commence on 6 April. On 4 April, Ministry of the Army and Navy ordered that all units of the 5th Army conduct a forced march to their position determined by the war plans. On 6 April, when the invasion of Yugoslavia began, the 34th Infantry Division "Toplička" and the 50th Infantry Division "Drinska" were completely mobilized, the 2nd Cavalry Division and the 8th Infantry Division "Krajinska" were partly mobilized and on their assigned positions, while the 9th Infantry Division "Timočka" was still in the process of mobilization.
