Also the roughness of the road forced them to dismount from their horses, so that if they would attack at all, it must be on foot.

This in the end they chose to do.

Many fell upon either side, though I myself received no wound, but in the end they drove us back.

Inch by inch they drove us back, or rather those who were left of us, at the point of their long lances, till at length they forced us into the mouth of the pass, that is some five furlongs distant from what was once the wall of the City of Pines.
To fight further was of no avail, here we must choose between death and flight, and as may be guessed, for wives' and children's sake if not for our own, we chose to fly.

Across the plain we fled like deer, and after us came the Spaniards and their allies like hounds.
