For this dishonor they themselves were the cause, the virtu of the soldiers was the cause of their not receiving injury. Whence the Romans, seeing this disaster, had recourse to the creation of a Dictator, so that one alone would restore that which three had destroyed. Whence the uselessness of many commanders in an army, or in a town that has to be defended is recognized: and Titus Livius could not more clearly state it with these forcible words: Three Tribunes with Consular power, proved how useless it was to give the conduct of the war to any; for each having his own counsel, each different from the others, they afforded the enemy [hosts] an opportunity to take advantage of the situation.
