(2) When Green says 800, he of course refers to the four regiments actually engaged in the assault; for, after losing, as he says, 261 of these 800, he makes the four regiments of Major's brigade, with two sections of Faries's battery, number 800; while his own force, with one section of Gonzales's battery, he puts at 750. 800 + 750 + 261 = 1,811. CHAPTER XX. IN SUMMER QUARTERS. Before Banks parted with Grover at Donaldsonville, he left orders for the troops to rest and go into "summer quarters" as soon as the pending operation should be decided. Accordingly, in the last days of July, Weitzel broke away from the discomforts of muddy, dusty, shadeless Donaldsonville, and marching down the bayou, once more took up his quarters near Napoleonville and Thibodeaux, and encamped his men at ease among the groves and orchards of the garden of La Fourche. On the 16th of July the steamboat _Imperial_, from St. Louis on the 8th, rounded to at the levee at New Orleans in token that the great river was once more free. The next day she set out on her return trip. On the 5th of August a despatch from Halleck, dated the 23d of July, was received and published in orders: "I congratulate you and your army on the crowning success of the campaign. It was reserved for your army to strike the last blow to open the Mississippi River. The country, and especially the great West, will ever remember with gratitude their services." Afterwards, on the 28th of January, 1864, Congress passed a joint resolution of thanks "to Major-General Nathaniel P. Banks and the officers and soldiers under his command for the skill, courage, and endurance which compelled the surrender of Port Hudson, and thus removed the last obstruction to the free navigation of the Mississippi River." Admiral Porter now came down the river to New Orleans in his flagship _Black Hawk_, and arranged to relieve Admiral Farragut from the trying duty of patrolling and protecting the river, so long borne by the vessels of his fleet. Farragut then took leave of absence and went North, leaving the West Gulf Squadron to Commodore Bell.
