reinforcements under the command of "Lucullus", mistakenly thought by Appian to be Lucius Licinius Lucullus, commander of the forces engaged in the Third Mithridatic War but who appears to have been the proconsul of Macedonia, Marcus Terentius Varro Lucullus, the former's younger brother. With Pompey's legions marching from the north and Lucullus' troops landing in Brundisium, Crassus realized that if he did not put down the slave revolt quickly, credit for the war would go to the general who arrived with reinforcements and he spurred his legions on to end the conflict quickly. Hearing of the approach of Pompey, Spartacus tried to negotiate with Crassus to bring the conflict to a close before Roman reinforcements arrived. When Crassus refused, Spartacus and his army broke through the Roman fortifications and headed up the Bruttium peninsula with Crassus's legions in pursuit. The legions managed to catch a portion of the rebels – under the command of Gannicus and Castus – separated from the main army, killing 12,300. Even though Spartacus had lost many men, Crassus' legions had also suffered greatly. The Roman forces under the command of a cavalry officer named Lucius Quinctius were destroyed when some of the escaped slaves turned to meet them. The rebel slaves were not a professional army and had reached their limit. They were unwilling to flee any farther and groups of men were breaking away from the main force to independently attack Crassus's legions. With discipline breaking down, Spartacus turned his forces around and brought his entire strength to bear on the legions. In this last stand, the Battle of the Silarius River, Spartacus' forces were routed, the vast majority of them being killed on the battlefield. All the ancient historians stated that Spartacus was also killed on the battlefield but his body was never found. Aftermath The rebels of the Third Servile War were annihilated by Crassus. Pompey's forces did not directly engage Spartacus's forces but his legions moving from the north were able to capture some 5,000 rebels fleeing the battle, "all of whom he slew". After this action, Pompey sent a dispatch to the Senate, saying that while Crassus certainly had conquered the slaves in open battle, he had ended the war, thus claiming a large portion of the credit and earning the enmity of Crassus. While most of the rebel slaves were killed on the battlefield, some 6,000 survivors were captured
