In 1958, Fidel Castroordered his revolutionary army to goon the offensive against the army of Fulgencio Batista. While Castro led one force against Guisa, Masó and other towns, another major offensive was directed at the capture of the city of Santa Clara, the capital of what was then Las Villas Province. Three columns were sent against Santa Clara under the command of Che Guevara, Jaime Vega, and Camilo Cienfuegos. Vega's column was caught in an ambush and completely destroyed. Guevara's column took up positions around Santa Clara. Cienfuegos's column directly attacked a local army garrison at Yaguajay. Initially numbering just 60 men out of Castro's hardened core of 230, Cienfuegos's group had gained many recruits as it crossed the countryside towards Santa Clara, eventually reaching an estimated strength of 450 to 500 fighters.
The battle
The garrison consisted of some 250 men under the command of a Cuban captain of Chinese ancestry, Alfredo Abon Lee. The attack seems to have started around the 19 December. Convinced that reinforcements would be sent from Santa Clara, Lee put up a determined defense of his post. The guerrillas repeatedly attempted to overpower Lee and his men, but failed each time. By the 26 DecemberCamilo Cienfuegos had become quite frustrated; it seemed that Lee could not be overpowered, nor could he be convinced to surrender. In desperation, Cienfuegos tried using a homemade tank against Lee's position. The "tank" was actually a large tractor encased in iron plates with attached makeshift flamethrowerson top. It, too, proved unsuccessful. Finally, on the 30 December Lee ran out of ammunition and was forced surrendered his force to the guerrillas.
Aftermath
The surrender of the garrison was a major blow to the defenders of the provincial capital of Santa Clara. The next day, the combined forces of Cienfuegos, Guevara, and local revolutionaries under William Alexander Morgan captured the city in a fight of vast confusion. Panicked by news of the defeat at Santa Clara and other losses, Batista fled Cuba the next day.
