Well, Pyrrhus did go to Sicily in 278-276 BC or so. Most of the island rallied to him since the Carthegians sort of thought he would just go away...which in fact he did eventually, but not quite as quickly as Mago (the Carthegian bigwig on the spot). Mago might have been able to get most of the western part of the island to move against Pyrrhus and in this case we have supposed that Pyrrhus has ambushed his ambushers crossing a river early in the morning. Pyrrhus is outnumbered in everything except heavy infantry, catapults and elephants, but he has the high ground in a central position and his enemies are in the middle of crossing a river at two points. Seems like a possible win for Pyrrhus. Here he has unleashed the elephants in the dawn's early light against the enemy light troops crossing the river. Note that Pyrrhus' Gauls are slower, but more cohesive (though less numerous):
