The Swedes were the first to yield in this game of starvation.  As their numbers grew their wants increased, and at length, furious with famine, they made a desperate assault upon the imperial camp.  They were driven back, with heavy loss.  Two weeks more Gustavus waited, and then, despairing of drawing his opponent from his works, he broke camp and marched with sounding trumpets past his adversary’s camp, who quietly let him go.  The Swedes had lost twenty thousand men, and Nuremberg ten thousand of her inhabitants, during this period of hunger and slaughter.

This was in September, 1632.  In November of the same year the two armies met again, on the plain of Luetzen, in Saxony, not far from the scene of Tilly’s defeat, a year before.  Wallenstein, on the retreat of Gustavus, had set fire to his own encampment and marched away, burning the villages around Nuremberg and wasting the country as he advanced, with Saxony as his goal.  Gustavus, who had at first marched southward into the Catholic states, hastened to the relief of his allies.  On the 15th of November the two great opponents came once more face to face, prepared to stake the cause of religious freedom in Germany on the issue of battle.

Early in the morning of the 16th Gustavus marshalled his forces, determined that that day should settle the question of victory or defeat.  Wallenstein had weakened his ranks by sending Count Pappenheim south on siege duty, and the Swedish king, without waiting for reinforcements, decided on an instant attack.

Unluckily for him the morning dawned in fog.  The entire plain lay shrouded.  It was not until after eleven o’clock that the mist rose and the sun shone on the plain.  During this interval Count Pappenheim, for whom Wallenstein had sent in haste the day before, was speeding north by forced marches, and through the chance of the fog was enabled to reach the field while the battle was at its height.

The troops were drawn up in battle array, the Swedes singing to the accompaniment of drums and trumpets Luther’s stirring hymn, and an ode composed by the king himself:  “Fear not, thou little flock.”  They were strongly contrasted with the army of their foe, being distinguished by the absence of armor, light colored (chiefly blue) uniforms, quickness of motion, exactness of discipline, and the lightness of their artillery.  The imperialists, on the contrary, wore old-fashioned, close-fitting uniforms, mostly yellow in color, cuirasses, thigh-pieces, and helmets, and were marked by slow movements, absence of discipline, and the heaviness and unmanageable character of their artillery.  The battle was to be, to some extent, a test of excellence between the new and the old ideas in war.
