The Battle of Las Carreras (Spanish: Batalla de Las Carreras) was a major battle during the years after the Dominican War of Independence and was fought on the 21–22 April 1849, nearby Baní, Peravia Province.

[1] As the remnants of the Haitian army retreated along the southern coastal road, they were under fire from a small Dominican squadron.

[1] Haitian strategy was ridiculed by the American press: [At the first encounter] ... a division of negro troops of Faustin ran, and their commander, Gen. Garat, was killed.

The main body, eighteen thousand troops, under the Emperor, encountered four hundred Dominicans with a field piece, and notwithstanding the disparity of force, the latter charged and caused the Haytiens to flee in every direction ... Faustin came very near falling into the enemy's hands.

The Dominicans pursued the retreating Haytiens some miles until they were checked and driven back by the Garde Nationale of Port-au-Prince, commanded by Robert Gateau, the auctioneer.
