Pelopidas

And yet the Spartans, who were of all men past masters in the art of war, trained and accustomed themselves to nothing so much as not to straggle or get into confusion upon a change of formation, but to take anyone without exception as neighbour in rank or in file, and wheresoever danger actually threatened, to seize that point and form in close array and fight as well as ever.

At this time, however, since the phalanx of Epaminondas bore down upon them alone and neglected the rest of their force, and since Pelopidas engaged them with incredible speed and boldness, their courage and skill were so confounded that there was a flight and slaughter of the Spartans such as had never before been seen. Therefore, although Epaminondas was boeotarch, Pelopidas, who was not boeotarch, and commanded only a small portion of the whole force, won as much glory for the success of that victory as he did.
