The 1831 Jamaican Black Regiment won the field against the militia.

Evidence

The rebels’ military core was the Black regiment, about one hundred and fifty strong with fifty guns among them. The Black Regiment, under the command of Colonel Johnson of Retrieve estate, fought a successful action on the 28th of December 1831 against the Western Interior militia, which had retreated from its barracks in the interior to Old Montpelier estate, near Montego Bay. … From there, the Black Regiment forced a further retreat to Montego Bay and put the country between Montego Bay, Lucea and Savannah-la-Mar in rebel hands. The Black Regiment then carried rebellion into the hills, invading estates and inviting recruits, burning properties on the border of St. James and setting off a trail of fires through the Great River Valley in Westmoreland and St. Elizabeth. — Cedric J.
