Hamilcar next moved to confront the army of Matho at Tunis. He divided his army, Hannibal took half of the soldiers and camped to the north of Tunis, Hamilcar camped to the south, thus hemming in Matho's army in Tunis. Hamilcar crucified Spendius and other rebel hostages outside Tunis to terrorize Matho, but this backfired when the rebels were able to surprise and defeat Hannibal's army due to their lax discipline. Punic survivors fled, all their baggage was captured along with Hannibal and thirty Carthaginian senators. Hamilcar retreated north near the mouth of Bagrades river, while Matho crucified his prisoners on the same crosses Hamilcar had used to crucify the rebel leaders, then retreated out of Tunis and moved south.
