After the surrender of Cornwallis, Washington again called the attention of Congress to Armand’s meritorious conduct, and he at last received his promotion as brigadier-general on the 26th of March, 1783. At the close of the war he was admitted as a member of the Society of the Cincinnati, and with warmest recommendations from Washington returned to his native country and lived privately until 1788, when he was elected one of twelve deputies to intercede with the king for the continuance of the privileges of his native province of Brittany. For this he was confined for several weeks in the Bastile. Upon his release he returned to Brittany, and in 1789, denounced the principle of revolution and proposed a plan for the union of the provinces of Brittany, Anjou, and Poitou, and the raising of an army to co-operate with the allies. These plans being approved by the brothers of Louis XVI., in December, 1791, Rouarie was appointed Royal Commissioner of Brittany. In March of the year following, the chiefs of the confederation met at his castle; and all was ready for action when they were betrayed to the legislative assembly, and troops were sent to arrest the marquis. He succeeded in eluding them for several months, when he was attacked by a fatal illness and died in the castle of La Guyomarais near Lamballe, on the 30th of January, 1793. THADDEUS KOSCIUSKO. Thaddeus Kosciusko, born near Novogrodek, Lithuania, on the 12th of February, 1746, was descended from a noble Polish family. Studying at first in the military academy at Warsaw, he afterward completed his education in France. Returning to his native country, he entered the army and rose to the rank of captain. Soon after coming to America, he offered his services to Washington as a volunteer in the cause of American independence. Appreciating his lofty character and fine military attainments, Washington made him one of his aids, showing the high estimation in which he held the gallant Pole. Taking part in several great battles in the North, Kosciusko there proved his skill and courage, and was ordered to accompany Greene to the South when that general superseded Gates in 1781. Holding the position of chief engineer, he planned and directed all the besieging operations against Ninety-Six. In recognition of these valuable services, he received from Congress the rank of brigadier-general in the Continental army on the 13th of October, 1783. Serving to the end of the war, he shared with Lafayette the honor of being admitted into the Society of the Cincinnati. Returning to Poland in 1786 he entered the Polish army upon its reorganization in 1789, and fought valiantly in behalf of his oppressed country. Resigning his commission, he once more became an exile, when the Russians triumphed, and the second partition of Poland was agreed upon.
