Spanish troops fighting the people of Santo Domingo, in the pass of Monte Christi, 1864.

Engagement between Spanish troops and people of the island of Santo Domingo, in the pass of Monte Christi, 1864. The Spanish annexed their former colonial territory on the island in 1861. The move was widely unpopular and a rebellion broke out against Spain's rule in 1863. The insurrection continued, with the rebels controlling the countryside and Spanish troops largely confined to the major towns, until 1865 when Queen Isabella II annulled the annexation.
