The untiring energy and zeal of Leandro Alem fitted him for being the chief organizer of a movement into which he threw himself heart and soul.
Here the efforts of Dr Alem succeeded in supplying a large body of rebels with arms and ammunition, and he was able, by a bold attack, to seize the town of Rosario and there establish the revolutionary headquarters.
Finding that the more conservative section of the union would not follow him, Alem formed a new association to which he gave the name of Union Civica Radical.
In April 1892 Alem and his chief colleagues were arrested and sent into exile.
But Alem was not content with constitutional opposition to the Acuerdo, and his movement soon assumed the character of a revolutionary propaganda against the national government.
The revolt speedily collapsed before this redoubtable commander, and Alem and the other leaders surrendered.
