The April general strike begins

The victory yielded weapons and reinforced the guerrillas’ capacity to resist larger government formations.

Che Guevara’s column established a rebel radio station that circulated news, instructions and political messages across Cuba.

Couriers and underground organizers carried equipment, messages and news between the guerrilla zone and urban networks.

Washington halted government arms deliveries as evidence of repression and political instability mounted, though previously supplied weapons remained in use.

A rebel appeal urged coordinated civil resistance, sabotage and armed action to remove Batista.

Police and military units killed or arrested activists, exposing weaknesses between the urban underground and guerrilla leadership.

Police and soldiers occupied workplaces and streets, while participating workers risked dismissal, arrest and death.

The broadcast defended the failed strike movement, condemned Batista’s repression and insisted that the armed struggle would continue.

Batista sent thousands of soldiers into the Sierra Maestra to destroy a much smaller rebel force.

The government offensive combined military pressure with bombing and forced movement in areas suspected of supporting the rebels.
