advantage of every success that their courage and valor gave them; and also to their officers, who were cool and determined throughout the action, fighting their commands against five times their number, and confident throughout of success. * * * "I would particularly call the attention of the department to Major F.E. Dumas, Capt. Villeverd and Lieuts. Jones and Martin, who were constantly in the thickest of the fight, and by their unflinching bravery and admirable handling of their commands, contributed to the success of the attack, and reflected great honor upon the flag for which they so nobly struggled."[33] The battle which settled for all time the bravery of black troops, and ought as well to silence all question about the capacity of colored officers, was the storming of Port Hudson, May 27, 1863. For months the Confederates had had uninterrupted opportunity to strengthen their works at Port Hudson at a time when an abundance of slave labor was at their disposal. They had constructed defenses of remarkable strength. On a bluff, eighty feet above the river, was a series of batteries mounting in all twenty siege guns. For land defenses they had a continuous line of parapet of strong profile, beginning at a point on the river a mile from Port Hudson and extending in a semi-circle for three or four miles over a country for the most part rough and broken, and ending again at the river, a half mile north of Port Hudson. At appropriate positions along this line four bastion works were constructed and thirty pieces of field artillery were posted. The average thickness of the parapet was twenty feet, and the depth of the ditch below the top of the parapet was fifteen feet. The ground behind the parapet was well adapted for the prompt movement of troops.[34] On the 24th of May General Banks reached the immediate vicinity of Port Hudson, and proceeded at once to invest the place.
