General Scott coming upon the battle-field about this juncture, ordered two brigades, under Shields, to move north and turn the right of the enemy.

This Shields did, but not without hard fighting and heavy loss.

The enemy finally gave way, leaving in our hands prisoners, artillery and small arms.

The balance of the causeway held by the enemy, up to the very gates of the city, fell in like manner.

I recollect at this place that some of the gunners who had stood their ground, were deserters from General Taylor's army on the Rio Grande.
Both the strategy and tactics displayed by General Scott in these various engagements of the 20th of August, 1847, were faultless as I look upon them now, after the lapse of so many years.
