The Battle of La Virgen occurred on the 3rd of September, 1855, at La Virgen, Nicaragua. It was part of the Legitimist efforts to resist the newly arrived force of William Walker, who had the support of the fierce opponents of the Legitimists, the Democrats. After a hard-fought but one-sided skirmish, Walker's forces emerged victorious, giving the cause of the invading Filibuster army legitimacy, and inspiring many new volunteers to join his force.
