• Accompanying text: We publish herewith a portrait of this gallant young hero, from a photograph kindly furnished by his family. The Philadelphia Inquirer gives the following sketch of his life: Lieutenant John T. Greble was a native of Philadelphia, and was the son of Edwin Greble, Esq. He passed examination in the Ringgold Grammar School at the age of twelve, as a candidate for the High School, at which latter institution he graduated at the age of sixteen. From the High School Mr. Greble went, under the nomination of the Hon. Lewis C. Levin, to the Military Academy at West Point, where he graduated high in his class on the 1st of July, 1854, taking his place in the army as a brevet Second Lieutenant. In September of the same year he was commissioned a Second Lieutenant in the Second Artillery, and was promoted to a First Lieutenancy on the 3d of March, 1857. After receiving his first commission, Lieutenant Greble was stationed for a few months at Newport Barracks, but was soon called to active service in Florida, to aid in protecting the inhabitants of that State from the depredations and murders of the much dreaded band of Seminoles under Billy Bowlegs. He served several years in this war, remaining until his regiment came home. His next service was upon the Academical Staff at West Point, as one of the Professors. In October, 1860, he was ordered to Fortress Monroe, where he was stationed until the 26th of May, 1861, at which time he went with his artillery command to the advanced post at Newport News. The sad termination of his brief but promising military career is told in the sorrowful intelligence made public yesterday. He was born in January, 1834, and was killed while gallantly heading his command in battle, on the morning of June 10, 1861, aged twenty-seven years. The particulars of this engagement show that the United States troops while advancing on Great Bethel were attacked by a masked rebel battery of forty rifled cannon, and that Lieutenant Greble was consequently ordered to bring up his guns. This movement he effected with great promptitude, and fired a number of shots, but without effect, in consequence of the commanding position of the enemy. A retreat was therefore rendered necessary. In making arrangements for the withdrawal of his guns, Lieutenant Greble was struck on the forehead and killed instantly. As an officer he bore the highest character. He was every inch a thorough-bred American soldier—skilled, brave, active, and efficient. In private life he was a gifted and accomplished gentleman, and every where he was beloved and esteemed.
