Thomas Pearson, A Forgotten Hero

Per Wikipedia:

Pearson attached part of his garrison to the pursuing British force under Lieutenant Colonel Morrison and led them at the decisive Battle of Crysler's Farm.
In 1814, Pearson led a detachment of light troops in the Niagara peninsula, and fought at the battles of Chippawa and Lundy's Lane, and in the Siege of Fort Erie, where he was wounded again.

From this site:

"...Pearson, a decorated and veteran light infantry officer, would prove to be one of the most troublesome opponents the United States faced during the War of 1812."

"The troops under his command slept clothed, with their muskets beside them; he permitted no boat traffic on the river in summer and no sleigh traffic in winter without a license signed by him. Although he did not attack the American bank of the St. Lawrence, he did organize an intelligence network of paid informers."

"Moving towards the British position, Scott was slowed by an advance guard led by Lieutenant Colonel Thomas Pearson. In the resulting Battle of Chippawa, Scott's men soundly defeated the British. The battle made Scott a hero and provided a badly needed morale boost (Map)."
