The Fusileers wore green "coatees" and Roman leather caps. The green frocks of the Rifles were trimmed with yellow fringe, a feature of the costume which is reputed to have originated the appellation "Katydids." In August the Artillery practiced at a target, and John S. King won a medal. Two years elapsed before Brooklyn was actually threatened with war. In 1814 the fear that the British fleet might, as in the Revolutionary descent, land at Gravesend, was naturally entertained. The committee of defense decided to build two fortified camps on Brooklyn Heights and on the heights of Harlem. Volunteers for labor on local and suburban defenses were called for, and there was a patriotic response. A company of students from Columbia Academy, Bergen, N. J., performed work on the Brooklyn Heights fortifications.[18] The Long Island defenses extended from the Wallabout to Fort Greene, to Bergen's Heights (on Jacob Bergen's property), and to Fort Lawrence. On the 9th of August, 1814, General Mapes, of New York, with a body of volunteers, broke ground for the intrenchments at Fort Greene. The work was carried on day by day by a different corps of volunteers. One day the labor would be performed by the tanners and curriers and the veteran corps of artillery; on another day, in happy unison, would be seen working, side by side, a brigade of infantry, a military association of young men, the Hamilton Society, and students of medicine; on another, a delegation from Flatbush would be seen engaged earnestly on the work; on another, the people of Flatlands would be armed with pick and shovel; then Gravesend dug in the trenches. Irishmen were not to be outdone; they proved their patriotism and love of liberty by volunteering, 1200 strong, to labor in the cause. Then the burghers from New Utrecht gave a helping hand. The free colored people gladly gave their aid. Jamaica came, headed by Dominie Schoonmaker, and with them came the principal of the academy, with his pupils. Workmen came from New York, Newark, Paulus Hook, and Morris County, N. J. A company came from Hanover Township, headed by their pastor, Rev. Dr. Phelps, and labored for a day upon these fortifications. So, too, the members of the Baptist Church in New York came, with their pastor, Rev. Dr. Archibald Macloy, and did a day's work. Rev. Dr. Macloy was the father of Congressman Macloy, who ably represented the seventh ward of New York and a part of Kings County before the late civil war.
