Henry Prince, one of the older general officers of the Union army, was born in Eastport, Maine, June 19, 1811, and was graduated from the Military Academy in the class of 1835. During the late thirties and early forties he fought in the Florida wars against the Seminoles and Creeks and was wounded at Camp Izard in 1836. During the war with Mexico, Prince was brevetted captain and major for gallantry as an officer of the 4th Infantry; he was so badly wounded at Molino del Rey that he was disabled for the next three years. In 1855 he accepted the staff appointment of major and paymaster; then after some years on frontier duty and another year on leave of absence because of his wounds, he was stationed in Washington until the outbreak of the Civil War. He was made a brigadier general of volunteers April 20, 1862, and commanded first a brigade and then Augur's division of Banks's corps. He was captured at Cedar Mountain on August 9 and held a prisoner until December. His principal field service after exchange was in the Rapidan campaign which followed R. E. Lee's retreat from Pennsylvania. Prince directed a division of French's III Corps in this campaign and at the affair of Mine Run was compelled to bear some of the onus for his commander's failure to engage the enemy. In 1864 and 1865 he was employed primarily in garrison command in Tennessee, Alabama, and South Carolina. At the end of the war he was brevetted brigadier general in the regular service; in the following years he served in the pay department, rising to the position of deputy paymaster general with rank of lieutenant colonel in 1877. On December 31, 1879, he was retired for age. Thirteen years later, on August 19, 1892, in a hotel on Trafalgar Square in London, Prince, then eighty-one-years-old and racked by his old wounds, committed suicide. His body was brought home and interred in Hillside Cemetery, Eastport, the town of his birth.
