Book 16
12.38

So, when Caesar had seen from a distance that the cavalry were looking for nothing except safety in flight, he spurred on his horse and held them back like a kind of barrier.

Do you know not that flight never leads to safety, but shows the folly of a useless effort? Let us return to our companions, to be at least sharers in their coming glory, if it is without consideration that we are abandoning them as they fight for their country.
