and 2 Illinois regiments formed the extreme left of our line and the former supported O'Brien's three pieces of artillery The commander on the left was Brigadier-general Lane.

Our left giving way, encouraged the enemy and large masses of them pressed forward and forced our light troops on the side of the mountain, to retire, and many of them could not be rallied until they reached the depot at Buena Vista. The 2nd Illinois regiment, to which a section of Sherman's battery was attached, were driven before the enemy.
The Mexican Infantry and cavalry poured in so rapidly that our rear was in danger. Thus far evidently, every move went against us.
