Then among Timoleon’s cavalry officers an astonishing strife and contention arose which delayed the battle.
For not one of them was willing to cross the river against the enemy after another, but each demanded to begin the onset himself, and their crossing was likely to be without order if they crowded and tried to run past one another.
Timoleon, therefore, wishing to decide their order by lot, took a seal-ring from each of the leaders, and after casting all the rings into his own cloak and mixing them up, he showed the first that came out, and it had by chance as the device of its seal a trophy of victory.
When the young men saw it, they cried aloud for joy and would no longer wait for the rest of the lot, but all dashed through the river as fast as they could and closed with the enemy.
