The English have asserted that they lost the Battle of Falkirk, in 1746, because of the severity of a snow-storm that took place when they went into action, a strong wind blowing the snow straight into their faces; and one of the causes of the defeat of the Highlanders at Culloden, three months later, was another fall of snow, which was accompanied by wind that then blew into their faces. Fortune was impartial, and made the one storm to balance the other.
That the American army was not destroyed soon after the Battle of Long Island must be attributed to the foggy weather of the 29th of August, 1776. But for the successful retreat of Washington’s army from Long Island, on the night of the 29th-30th, the Declaration of Independence would have been made waste paper in “sixty days” after its adoption; and that retreat could not have been made, had there not been a dense fog under cover of which to make it, and to deter the enemy from action. Washington and his whole army would have been slain or captured, could the British forces have had clear weather in which to operate. “The fog which prevailed all this time,” says Irving, “seemed almost Providential. While it hung over Long Island, and concealed the movements of the Americans, the atmosphere was clear on the New York side of the river. The adverse wind, too, died away, the river became so smooth that the rowboats could be laden almost to the gunwale; and a favoring breeze sprang up for the sail-boats. The whole embarkation of troops, ammunition, provisions, cattle, horses, and carts, was happily effected, and by daybreak the greater part had safely reached the city, thanks to the aid of Glover’s Marblehead men. Scarce anything was abandoned to the enemy, excepting a few heavy pieces of artillery. At a proper time, Mifflin with his covering party left the lines, and effected a silent retreat to the ferry. Washington, though repeatedly entreated, refused to enter a boat until all the troops were embarked, and crossed the river with the last.” Americans should ever regard a fog with a certain reverence, for a fog saved their country in 1776.
