Quadripartite Pact

In 1936, Spanish Nationalists were in the midst of the final preparations for their coup d'etat. The time for the coup was set at July 18 for Morocco, and the following day for Spain proper. The coup was intended to be a hasty takeover of the Spanish Republic -- however it was everything but. The conflict known as the Spanish Civil War lasted three years, finally ending in a Nationalist victory -- but what if it wasn't? What if, due to increased Axis support and higher initial gains, the coup ended much sooner?
