4 SEP--This Day in US Military History

1812 – The Siege of Fort Harrison begins when the fort is set on fire.

A band of Miami arrived and warned Captain Zachary Taylor that they would soon be attacked by a large force of Native Americans. That evening, shots were heard, but Taylor was hesitant to send a scout party. He only had 50 men in his garrison, and sickness had reduced the number of effective soldiers to only 15. In the morning, a party was dispatched and discovered the bodies of two white settlers, the Doyle brothers. The brothers were buried, and the party reported back to Fort Harrison.
Captain Taylor, with his 15 able soldiers and about 5 healthy settlers, made ready for the expected attack. Each of the 20 men was issued sixteen rounds to fire. That day, September 4, a force of 600 Potawatomi (under Chief Pa-koi-shee-can), Wea (under War Chief Stone Eater), Shawnee, Kickapoo and Winnebago warriors approached Fort Harrison. A party of 40 men under command of Kickapoo Chief Namahtoha approached under a flag of truce and asked to parley with Taylor the next morning. Taylor agreed, and the Indian force retreated to camp for the night.
That night, a warrior crawled up and set the blockhouse on fire. When the sentries opened fire on the arsonist, the 600-strong Indian war party attacked the west side of the fort. Taylor ordered the fort’s surgeon and a handful of defenders to control the fire. The blockhouse, which was attached to the barracks, had a store of whiskey, which soon ignited, and the fire raged out of control. Taylor admitted in his report that the situation looked hopeless, and two of his healthy men fled the fort. Warning the fort that “Taylor never surrenders!”, the captain organized a bucket brigade to fight the fire before it destroyed the fort’s picket walls. One woman, Julia Lambert, even lowered herself down into the fort’s well to fill buckets more quickly.
The fire did serve one purpose, in that it illuminated the night, revealing the attackers. The fire left a 20-foot-wide (6.1 m) gap in the outer wall, which the garrison temporarily sealed with a 5-foot-high (1.5 m) breastwork. The remaining few of the garrison returned the fire of the Indians so fiercely that they were able to hold off the attack. All remaining invalids were armed to maintain defense, while healthy men were put to work repairing a hole left in the fort’s walls.
The fort was repaired by daybreak of September 5. The Indian force withdrew just beyond gun range and butchered area farm animals within sight of the fort. The garrison and settlers inside the fort, meanwhile, had lost most of their food in the fire, and had only a few bushels of corn, and faced starvation. News of the siege arrived in Vincennes as Colonel William Russell was passing through with a company of regular infantry and a company of rangers, on their way to join Ninian Edwards, governor of Illinois Territory. Colonel Russell’s companies joined with the local militia and 7th Infantry Regiment and marched to the relief of Fort Harrison. Over 1000 men arrived from Vincennes on September 12, and the Indian force departed. The next day, however, a supply train following Colonel Russell was attacked in what became known as the Attack at the Narrows in modern Sullivan County, Indiana.
