Soon after he arrived on the lakes, in 1815, he was placed in a situation that strongly marked that benevolence which was so strong a feature in his character. In the winter he was in command of a blockhouse on Lake Huron, with a party of men, for the purpose of defending it: he had only one small gun for its defence; he was attacked by an American schooner; the blockhouse was soon demolished by the superiority of the enemy’s fire; and he found that himself and the party must either become prisoners of war, or form the resolution of immediately crossing Lake Michigan upon the ice, a journey of nearly sixty miles, to York, the capital of Upper Canada, and the nearest British depot. Notwithstanding the difficulty and danger attending a journey of such length over the ice in the depth of winter, the alternative was soon adopted, and the party set out to cross the lake, but had not gone more than ten or twelve miles, before a boy, one of the party, was unable to proceed from the cold; every one of the sailors declared that they were unable to carry him, as they were so benumbed with the cold, and had scarcely strength sufficient to support themselves. Clapperton’s generous nature could not bear the idea of a fellow-creature being left to perish under such appalling circumstances, for a dreadful snow-storm had commenced; he therefore took the boy upon his back, holding him with his left hand, and supporting himself from slipping with a staff in his right. In this manner he continued to go forward for eight or nine miles, when he perceived that the boy relaxed his hold; and on Clapperton examining the cause, he found that the boy was in a dying state from the cold, and he soon after expired. The sufferings of the whole party were great before they reached York; the stockings and shoes completely worn off their feet; their bodies in a dreadful state from the want of nourishment, they having nothing during the journey except one bag of meal. From the long inaction of Clapperton’s left hand, in carrying the boy upon his back, he lost, from the effects of the frost, the first joint of his thumb.
