Winning in Santiago de Cuba without a fight

The two Castro brothers with their army arrived on the outskirts of Santiago de Cuba and said their forces would storm the city at 6 PM 1 January if it did not first surrender. The commander (Colonel Rego Rubido) surrendered Santiago de Cuba without a fight. The war was over and Fidel was able to take power in Havana when he arrived on 8 January 1959.
