MR-26-7 members led an armed uprising days of intermittent attacks

The plan had been for the crossing to take 5 days, and on the Granma's scheduled day of arrival, 30 November, MR-26-7 members ("26th of July Movement") under Frank País led an armed uprising in Santiago and Manzanillo. However, the Granma's journey ultimately lasted 7 days, and with Castro and his men unable to provide reinforcements, País and his militants dispersed after two days of intermittent attacks.
