In the first year of the war (1846) three regiments of volunteers were raised in Indiana to serve for twelve months. These regiments rendezvoused at New Albany in the summer of 1846 and Joseph LANE (then Colonel of the Second regiment) was chosen to command the brigade, and Wm. A. BOWLES was promoted to the colonelcy of the Second regiment. The Indiana brigade proceeded down the river to New Orleans, thence across the Gulf of Mexico to Brazos Santiago at the mouth of the Rio Grande. The Second and Third regiments were ordered to join Gen. TAYLOR's forces, then at Monterey. The 1st regiment with other troops remained on the lower Rio Grande to keep open communication with the mouth of the river. I present below a full roster of Capt. Henry DAVIS' company: CO. F.
