In 1891, Major Mark Wainwright leads another stab into Kansas from Nebraska, testing the defenses of a new fort near Concordia. The fort repels them, but Wainwright reports back to Colonel Theodore Monteith that the fort is ripe for a full-scale assault. Monteith assembles a force of almost 3000 men and places them at Wainwright's disposal. The Kansans, for their part, send reinforcements to Concordia to see if they can trap the Unionists with hopes of finding a weakened fort.
