" Che” Guevara with about two thousand guerrilla fighters entered Havana on January 2, 1959. Their entry was relatively quiet as they headed for the Malecon and the old Spanish fortress, overlooking the entrance of Havana harbor. At 3:00 a.m. early the following morning, they took over the imposing La Cabaña fortress. In anticipation of Guevara’s arrival the three thousand regular army soldiers, assigned to the fort, stood in formation as their officers greeted Guevara. Addressing the troops, “Che” light-heartedly told them that they could teach his men how to march, but that his rebels could teach them how to fight.
When they were dismissed, he had them turn in their rifles but allowed the officers to retain their pistols. He granted them all a month’s furlough; however, upon their return they discovered that they had all been relieved of duty and permanently discharged. "
