Marshal Horn threw a barricade across this and defended it until nightfall.

Tilly had then fallen back before the advance of Gustavus to a very strong position on the Lech.

This was an extremely rapid river, difficult to cross and easily defensible.

Tilly had broken down the bridges, and was prepared to dispute till the last the further advance of the Swedes.

He placed his army between Rain, where the Lech falls into the Danube, and Augsburg, a distance of sixteen miles--all the assailable points being strongly occupied, with small bodies of cavalry in the intervals to give warning of the approach of the enemy.
