The stale and stereotyped falsehood that the blacks are wanting in patriotism, was nailed to the counter as base coin, on the banks of the Mississippi. Many Persians were slain at the battle of Thermopylæ, but history records only the fall of Leonidas and his four hundred companions. So, in the future, when we shall have passed away from the stage, and rising generations shall speak of the conflict at Port Hudson, and the celebrated charge of the Negro Brigade, they will forget all others, in their admiration for Captain Callioux and his black associates. I should have said, the expedition against this strongly fortified place was Major-General Banks's, under whom the other officers acted. The commander, in his official report of the engagement, bears the following testimony to the bravery of the colored troops. He says,-- "On the extreme right of our lines I posted the first and third regiments of negro troops. The first regiment of Louisiana engineers, composed exclusively of colored men, excepting the officers, was also engaged in the operations of the day. The position occupied by these troops was one of importance, and called for the utmost steadiness and bravery in those to whom it was confided. "It gives me pleasure to report that they answered every expectation. In many respects their conduct was heroic; no troops could be more determined or more daring. They made, during the day, three charges upon the batteries of the enemy, suffering very heavy losses, and holding their position at nightfall with the other troops on the right of our lines. The highest commendation is bestowed upon them by all the officers in command on the right. "Whatever doubt may have existed heretofore as to the efficiency of organizations of this character, the history of this day proves conclusively to those who were in condition to observe the conduct of these regiments, that the government will find in this class of troops effective supporters and defenders. The severe test to which they were subjected, and the determined manner in which they encountered the enemy, leaves upon my mind no doubt of their ultimate success." The Hon. B. F. Flanders, writing from New Orleans, under date of June 2, 1863, pays the following tribute to the bravery of those invincible men:-- "The unanimous report of all those who were in the recent severe fight at Port Hudson, in regard to the negroes, is, that they fought like devils. They have completely conquered the prejudice of the army against them. Never was there before such an extraordinary revolution of sentiment as that of this army in respect to the negroes as soldiers." CAPTAIN JOSEPH HOWARD. "Freemen, now's your day for doing-- Great the issues in your hand; Risk them not by faint pursuing, Peal the watchword through the land: On for Freedom, God, our Country, and the Right!"
