On June 17, 1845, small Dominican detachments invaded Haiti, capturing Lascahobas and Hinche. The Dominicans established an outpost at Cachimán, but the arrival of Haitian reinforcements soon compelled them to retreat back across the frontier. Haiti launched a new invasion on August 6. The Dominicans repelled the Haitian forces, on both land and sea, by December 1845.
