"We are at all points on the threshold of his fortifications," the order continues. "Only one more advance, and they are ours!
"For the last duty that victory imposes, the Commanding General summons the bold men of the corps to the organization of a storming column of a thousand men, to vindicate the flag of the Union, and the memory of its defenders who have fallen! Let them come forward!
"Officers who lead the column of victory in this last assault may be assured of the just recognition of their services by promotion; and every officer and soldier who shares its perils and its glory shall receive a medal to commemorate the first great success of the campaign of 1863 for the freedom of the Mississippi. His name will be placed in General Orders upon the Roll of Honor."
Colonel Henry W. Birge, of the 13th Connecticut, at once volunteered to lead the stormers, and although the whole project was disapproved by many of the best officers and men in the corps, partly as unnecessary and partly because they conceived that it implied some reflection upon the conduct of the brave men that had fought and suffered and failed on the 27th and the 14th, yet so general was the feeling of confidence in Birge that within a few days the ranks of the stormers were more than filled. As nearly as can now be ascertained, the whole number of officers who volunteered was at least 80; of enlisted men at least 956. Of these, 17 officers and 226 men belonged to the 13th Connecticut. As the different parties offered and were accepted, they were sent into camp in a retired and pleasant spot, in a grove behind the naval battery on the right. On the 15th of June Birge was ordered to divide his column into two battalions, and to drill it for its work. On the 28th this organization was complete. The battalions were then composed of eight companies, but two companies were afterwards added to the first battalion. To Lieutenant-Colonel Van Petter, of the 160th New York, Birge gave the command of the first battalion, and to Lieutenant-Colonel Bickmore, of the 14th Maine, that of the second battalion. On that day, 67 of the officers and 826 men—in all, 893, were present for duty in the camp of the stormers. Among those that volunteered for the forlorn hope but were not accepted were 54 non-commissioned officers and privates of the 1st Louisiana Native Guards, and 37 of the 3d. From among the officers of the general staff and staff departments that were eager to go, two were selected to accompany the column and keep up the communication with headquarters and with the other troops; these were Captain Duncan S. Walker, assistant adjutant-general, and Lieutenant Edmund H. Russell, of the 9th Pennsylvania Reserves, acting signal officer.
Then the officers and men quietly prepared themselves for the serious work expected of them. Those that had any thing to leave made their wills in the manner sanctioned by the custom of armies, and all confided to the hands of comrades the last words for their families or their friends.
Meanwhile an event took place, trifling in itself, yet accenting sharply some of the more serious reasons that had, in the first instance, led Banks to resist the repeated urging to join Grant with his whole force, and afterward had formed powerful factors in determining him to deliver and to renew the assault. Early on the morning of the 18th of June a detachment of Confederate cavalry rode into the village of Plaquemine, surprised the provost guard, captured Lieutenant C. H. Witham and twenty-two men of the 28th Maine, and burned the three steamers lying the bayou, the Sykes, Anglo-American, and Belfast. Captain Albert Stearns, of the 131st New York, who was stationed at Plaquemine as provost marshal of the parish, made his escape with thirteen men of his guard. The Confederates were fired upon by the guard and lost one man killed and two wounded. In their turn they fired upon the steamboats, and wounded two of the crew. Three hours later the gunboat Winona, Captain Weaver, came down from Baton Rouge, and, shelling the enemy, hastened their departure. In the tension of greater events, little notice was taken at the moment of this incident; yet it was not long before it was discovered that the raiders were the advance guard of the little army with which Taylor was about to invade La Fourche, intent upon the bold design of raising the siege of Port Hudson by blockading the river and threatening New Orleans.
Thus Banks was brought face to face with the condition described in his letter of the 4th of June to Halleck:
"The course to be pursued here gives me great anxiety. If I abandon Port Hudson, I leave its garrison, some 6,000 or 7,000 men, the force under Mouton and Sibley, now threatening Brashear City and the Army of Mobile, large or small, to threaten or attack New Orleans. If I detach from my command in the field a sufficient force to defend that city, which ought not to be less than 8,000 or 10,000, my assistance to General Grant is unimportant, and I leave an equal or larger number of the enemy to reinforce Johnston. If I defend New Orleans and its adjacent territory, the enemy will go against Grant. If I go with a force sufficient to aid him, my rear will be seriously threatened. My force is not large enough to do both. Under these circumstances, my only course seems to be to carry this post as soon as possible, and then to join General Grant. If I abandon it I cannot materially aid him."
Taylor's incursion caused Banks some anxiety and appreciable inconvenience, without, however, exercising a material influence on the fortunes of the siege; accordingly, it will be better to reserve for another chapter the story of this adventure.
About the same time, Logan again became troublesome. At first he seems to have thought of retiring on Jackson, Mississippi; but this Johnston forbade, telling him to stay where he was, to observe and annoy the besiegers, and if pressed by too strong a force, to fall back only so far as necessary, hindering and retarding the advance of his assailants. By daylight, on the morning of the 15th of June, Logan dashed down the Clinton road, surprised the camp of the 14th New York cavalry, who made little resistance, and the guard of the hospital at the Carter House, who made none. In this raid Logan took nearly one hundred disabled prisoners, including six officers, and carried off a number of wagons. However, finding Grierson instantly on his heels, Logan promptly "fell back as far as necessary." On the evening of the 30th of June, while hovering in the rear of Dwight, Logan captured and carried off Brigadier-General Dow, who, while waiting for his wound to heal, had taken up his headquarters in a house some distance behind the lines. At daylight, on the morning of the 2d of July, Logan surprised the depot at Springfield Landing, guarded by the 162d New York, Lieutenant-Colonel Blanchard, and a small detachment of the 16th New Hampshire, under Captain Henry. Careless picket duty was the cause, and a great stampede the consequence, but Logan hardly stayed long enough to find out exactly what he had accomplished, since he reports that, besides burning the commissary and quartermasters' stores, he killed and wounded 140 of his enemy, captured 35 prisoners, fought an entire brigade, and destroyed 100 wagons, with a loss on his part of 4 killed and 10 wounded; whereas, in fact, the entire loss of the Union army was 1 killed, 11 wounded, 21 captured or missing, while the stores burned consisted of a full supply of clothing and camp and garrison equipment for about 1,000 men. The wagons mentioned by Logan were part of a train met in the road, cut out, and carried off as he rapidly rode away, and the number may be correct.
