To carry out the agreement thus entered into, the following general order was issued by General Twiggs:

General orders, no. 5.

Headquarters Department of Texas, San Antonio, February 18, 1861.

The State of Texas, having demanded through its commissioners the delivery of military posts and property within the limits of this command; and the commanding general, desiring to avoid even the possibility of a collision between the Federal and State troops, the posts will be evacuated by their garrisons, and these will take up, as soon as the necessary preparations can be made, their line of march out of Texas by way of the coast; marching out with their arms (the light batteries with their guns), clothing, camp and garrison equipage, quartermaster stores, subsistence, medical, hospital stores, and such means of transportation of every kind as may be necessary for an efficient and orderly movement of the troops, prepared for attack or defense against aggressions from any source. The troops will carry with them provisions as far as the coast.

By order of Brevet Major-General Twiggs:

A. N. Nichols, Assistant Adjutant-General.

That was his last order, he being relieved of his command the next day, the 19th of February, 1861, by Colonel Waite assuming command of the department under an appointment previously made.

The commissioners appointed agents to take charge of the public property after the evacuation of the Federal troops, and there being no longer any use for the volunteer forces of Col. Ben McCulloch, they were disbanded and returned to their homes. Ben McCulloch returned to Austin, and after getting an order for 1,000 guns for the State resigned his office.
