The climax of the campaign was on September 23, 1861, at Osceola, where Lane's forces drove off a small Southern force and then looted and burned the town. According to reports, many of the Kansans got so drunk that when it came time to leave they were unable to march and had to ride in wagons and carriages. They carried off with them a tremendous load of plunder, including as Lane's personal share a piano and a quantity of silk dresses.
Osceola was plundered with Lane's men freeing 200 slaves and taking 350 horses, 400 cattle, 3,000 bags of flour, and quantities of supplies from all the town shops and stores as well as carriages and wagons. Nine local men were rounded up, given a quick drumhead court-martial trial, and executed. All but three of the town's 800 buildings burned; the town never fully recovered.
