Inuyama Castle fell, and with Saito Ryuko now isolated and alone, Harano's two thousand men were nothing more than the cherry on top for Oda Nobunaga. Nobunaga didn't want to keep feeding them either, so after giving them a share of the spoils, he subtly hinted they could head home.
Yeah, what Harano got from the spoils was mostly a portion of Inuyama Castle's population. The land, castles, and wealth went to Oda Nobunaga, while Harano took away part of the population. Consider it an ally's reward for winning together.
