The relations of the States became more amicable in the early years of the century, the rival commonwealths being drawn together by a general obligation of self-defense as against England. In 1808 had come Jefferson's Embargo Act, of whose influence in New York John Lambert writes: "Everything wore a dismal aspect at New York. The embargo had now continued upwards of three months, and the salutary check which Congress imagined it would have upon the conduct of the belligerent powers was extremely doubtful, while the ruination of the commerce of the United States appeared certain if such destructive measures were persisted in. Already had 120 failures taken place among the merchants and traders, to the amount of more than 5,000,000 dollars; and there were above 500 vessels in the harbor which were lying up useless, and rotting for want of employment. Thousands of sailors were either destitute of bread, wandering about the country, or had entered the British service. The merchants had shut up their counting-houses and discharged their clerks; and the farmers refrained from cultivating their land; for if they brought their produce to market they could not sell it at all, or were obliged to dispose of it for only a fourth of its value."
Elsewhere in his journal, Lambert writes: "The amount of tonnage belonging to the port of New York in 1806 was 183,671 tons, and the number of vessels in the harbor on the 25th of December, 1807, when the embargo took place, was 537. The moneys collected in New York for the national treasury, on the imports and tonnage, have for several years amounted to one fourth of the public revenue. In 1806 the sum collected was 6,500,000 dollars, which, after deducting the drawbacks, left a net revenue of 4,500,000 dollars, which was paid into the treasury of the United States as the proceeds of one year. In the year 1808 the whole of this immense sum had vanished!"
In June, 1812, came the declaration of war with Great Britain. The news occasioned considerable excitement in Brooklyn, whose middle-aged men retained a lively recollection of the British occupation. In the "Star" of July 8 appeared this announcement: "A new company of Horse or Flying Artillery is lately raised in this vicinity, under the command of Captain John Wilson. This company promises, under the able management of Captain Wilson, to equal, if not excel, any company in the State. The Artillerists of Captain Barbarin are fast progressing in a system of discipline and improvement, which can alone in the hour of trial render courage effectual. We understand this company have volunteered their services to Government, and are accepted. The Riflemen of Captain Stryker and the Fusileers of Captain Herbert are respectable in number and discipline. The county of Kings is in no respect behind her neighbors in military patriotism."
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.
The erection of the defenses of Brooklyn was thus not a local affair. It was one in which the neighboring cities, towns, and States took part. The people were enthusiastic. The Grand Lodge of Masons enlisted in the service, and the watchword of the day was: "The Master expects every Mason to do his duty." Old Fortitude Lodge, which still exists, rendered a day's service. A company of ladies came from New York, forming a procession, with music, marched to Fort Greene, and used the shovel and the spade for several hours. The people had one mind and were actuated by one purpose. The work advanced rapidly, for, as in the days of Nehemiah, the "people had a mind to work," and their efforts were crowned with success. These were the times when the people willingly gave their money for the good of the country, without expecting to receive it again with compound interest.
Early in September the works were completed. The Twenty-second Brigade of Infantry, composed of 1750 men, was stationed within the lines. Heavy artillery was mounted. Brigadier General Jeremiah Johnson was in command. He was a natural soldier, and possessed every element of character necessary to lead a brigade. Stern and unflinching in the performance of duty, he yet had a warm and generous heart, which led him to take an active interest in the welfare of the men in his command. The soldiers loved him, and rendered willing obedience to his orders. Being a resident of Brooklyn, he knew or was known by most of his men personally.
At the fort on Cobble Hill worked military companies under command of Captains Stryker, Cowenhoven, and Herbert, the "exempts" of Bedford and the Wallabout, Fire Company No. 2 of Brooklyn, and a company of Bushwick people headed by Pastor Bassett. "Next to the duties which we owe to Heaven," said the Bushwick people at their meeting, "those which belong to our country demand our chief attention."
The volunteers worked with the utmost zeal, laboring by moonlight when sunset still left work to do. The Sixty-fourth Regiment, of Kings County, was commanded by Francis Titus, with Albert C. Van Brunt as second major, and Daniel Barre as adjutant. New Utrecht's company was headed by Captain William Dewyre; Brooklyn's company was headed by Captain Joseph Dean; the Wallabout and Bushwick company, by Captain Francis Stillman; the Gowanus company, by Captain Peter Cowenhoven, and later by Captain John T. Bergen; the Gravesend and Flatbush companies, by Captain Jeremiah Lott.
