Sir Patrick Ruthven advanced along the shores of Lake Constance, driving the Imperialists before him into the Tyrol.

Magdeburg was captured by General Banner, the Landgrave of Hesse-Cassel reduced all Fulda-Paderborn and the adjacent districts, the Elector of Saxony overran Bohemia, and Sir Alexander Leslie threatened the Imperialists in Lower Saxony.
Thus the campaign of 1632 opened under the most favourable auspices.

The Green Brigade marched on the 5th of March to Aschaffenburg, a distance of more than thirty miles, a fact which speaks volumes for the physique and endurance of the troops, for this would in the present day be considered an extremely long march for troops, and the weight of the helmet and armour, musket and accoutrements, of the troops of those days was fully double that now carried by European soldiers.

Here they were reviewed by the king.
By the 10th the whole army, 23,000 strong, were collected at Weinsheim and advanced towards Bavaria, driving before them the Imperialists under the Count de Bucquio.

The Chancellor Oxenstiern had been left by the king with a strong force to guard his conquests on the Rhine.
No sooner had the king marched than the Spaniards again crossed the Moselle.
