Bussa's Rebellion failed. The uprising was triggered prematurely, but the slaves were already greatly outmatched. Barbados' flat terrain gave the horses of the better-armed militia the clear advantage over the rebels, with no mountains or forest for concealment. Slaves had also thought they would be supported by freed men of colour, but these instead joined efforts to quell the rebellion. Although they drove whites off the plantations, widespread killings did not take place. By the end, 120 slaves died in combat or were immediately executed and another 144 brought to trial and executed. The remaining rebels were shipped off the island.
