After starting upon his journey, circumstances arose which recalled him temporarily; but toward the end of October, in 1862, he reached Texas.

General Magruder early realized the necessity of holding the line of the Rio Grande, which for more than twelve hundred miles was the boundary between the Confederate states and the Republic of Mexico. Along so many hundreds of miles of waterway, and a line which presented a great many military difficulties, it was impossible for the United States, without a base on the Gulf of Mexico, to interrupt or prevent the transportation and sale of cotton and the return of supplies through Mexico, which at that time were almost absolutely necessary to maintain an organized army in Texas. The preservation of this territory was a military necessity. It divided the Federal forces and kept a great number of men engaged in defending the flanks of the armies operating along the Mississippi River and the Gulf of Mexico.

Up to the time of Magruder’s coming, those in command in Louisiana and Texas had practically conceded that a full defence of the Texan coast was impracticable. Galveston, by reason of its peculiar topographical position, had been abandoned. A small Federal force was quartered on the wharves, close to the limits of the city, while the Federal fleet, outside, prevented egress and ingress to the harbor, and only waited reinforcements to make a more permanent and extensive occupation and by closing the avenues to Mexico, make complete the blockade of the entire borders of the Confederacy.

General Magruder was considered one of the best strategists in the Confederate army. By quick movements and the rapid disposition of troops, he had delayed General McClellan’s march along the Yorktown Peninsula several weeks, and he was now resolved to rid the coast of Texas of Federal invasion and to restore Galveston to Confederate control. He had but few of the more powerful resources of military arts at his command; his artillery was limited; he had no gunboats and no material from which to make a gunboat that could ride the ocean storms; but his coming with a magnificent past of military achievement, and his personal confidence and courage, quickly inspired the people in the proximity of Galveston with the highest opinions of his talents and gallantry, and created hope where the surroundings declared there could be no hope.

It is fifty miles from Houston to Galveston, and the Brazos River, together with the bayous, afforded communication with the Gulf, through the harbor at Galveston to that city. Prompt in action and resolute of purpose, General Magruder reconnoitered the situation at Galveston, and determined to re-take the place. He only proposed to make this attempt after a very careful survey and an equally careful arrangement of his plans. The Federal fleet blockading Galveston was not very extensive, yet was so out of proportion to anything that the Confederates could bring to bear upon it, that an attack on it was considered absolutely foolhardy.

General Magruder had brought with him from Virginia a few hundred Enfield rifles. These proved of tremendous value in the operations he was to undertake at Galveston. Shotguns and ordinary hunting rifles were not very satisfactory, unless at very close range, and while General Magruder may not have anticipated such service as they should render at Galveston, it was deemed by his followers extremely fortunate that he had the foresight to introduce, with his coming to his new field of operation, these English guns.

Among Federal vessels blockading the port at Galveston was the Harriet Lane, commanded by Captain Wainwright; she carried four heavy guns and two twenty-four-pounders. The Westfield, mounting eight guns, was a large propeller, and the flagship of Commodore Renshaw, in command of the blockading fleet. The Owasco, another propeller, carried eight heavy guns; the Clifton, a propeller with four heavy guns and an armed schooner were among the vessels which composed the fleet which General Magruder, with the most inadequate means, proposed to attack and destroy, or put to flight.

As early as the beginning of 1863, the Confederate cavalry had been taught to be ready for any service, whether in scouting, raiding, assaulting infantry or defending forts. In the demands upon cavalry, the Confederate authorities were no respecter of persons, and that a man belonged to the cavalry gave him no exemption from any service that infantry or artillery could perform.

By the 1st of November, 1862, General Magruder issued a call for volunteers. Hand bills were distributed throughout the city of Houston, calling for enlistments. It had been given out that Captain Leon Smith would have charge of the operations by water. These calls received few responses. Some said it was the hazard of the expedition, others were unwilling to volunteer under Captain Smith, a stranger. Call after call fell on deaf ears, and incredible minds and unwilling hearts, so far as the citizens and the sailors about Houston were concerned.

General Magruder’s plans seemed doomed to failure, when Lieutenant Colonel Bagby of the cavalry suggested to General Magruder that Colonel Tom Green was a man of boundless courage and also of unlimited resources. The history of General Green’s intrepidity, fortitude, and superior ability in extricating his brigade from New Mexico a few months before had spread abroad through Texas, and after this superb performance, many people thought there was nothing that General Green could not accomplish.
