The Varangian Major Halmarson took command of the brigade attacking the western bridge near the village of Gallo. He had four infantry battalions and the heavy cannon from Civita Maria. The enemy did not fortify much, nor did they construct a bridgehead. The enemy Colonel was a rich citizen of one of the southern cities, with a volunteer provincial light infantry detachment of a hundred and twenty, and two standard strength provincial battalions under his command. He was smart enough to raise a redoubt, but on the wrong side of the bridge.
