August 1631 CE
Tilly invades Electoral Saxony because, first, it is the shortest distance between himself and Gustav’s flank; second, because he hopes to force its ruler to abandon any planned alliance with Gustav; and third, because the Saxon territories offer plenty of food and sustenance for his exhausted army.
His plan is to avoid contact with the Swedes, and ultimately the Saxons, until his troops can unite with the units near Jena (about five thousand seasoned professionals), and the larger force of Count Otto von Fugger, en route from Hesse.
Gustav and John George unite their forces, planning to meet Tilly somewhere near Leipzig.
When Tilly attacks the Electorate of Saxony, the Saxon electors join their forces with the Swedish army.
