When the Convention of Virginia met to consider the question of secession, the slave-holding dignitaries were somewhat startled by the logical, but novel, declaration of one of the western members, that "the right of revolution can be exercised as well by a portion of the citizens of a State against their State government, as it can be exercised by the whole people of a State against their Federal Government." This was followed by another, more pointed and revolutionary, "that any change in the relation Virginia now sustains to the Federal Government, against the wishes of even a respectable minority of her people, would be sufficient to justify them in changing their relation to the State government by separating themselves from that section of the State that had thus wantonly disregarded their interests and defied their will."

The convention, however, denying the pertinency of this logic, passed its secret ordinance of secession on the 17th day of April, and within a week popular movements were on foot in the various towns and counties of Western Virginia, to effect a division of the State. The people united in a unanimous protest against the efforts of the slave-holding aristocrats to carry them into a cotton confederacy, and a determination to "secede from secession," was manifested everywhere. The loyal determination was rapidly followed by popular organization, an appeal for assistance was made to the government at Washington, who promised them countenance and support, and on the 13th day of May, delegates from twenty-five counties of West Virginia met at Wheeling, to devise such action as would enable them to fully and finally repudiate the treasonable revolt of East Virginia.

Many circumstances favored their position. The state of Ohio, immediately adjoining, was organizing her military force of volunteers, and Western Virginia was, not long after, attached to the department of the Ohio under command of General McClellan. The blockade of Washington, and other events, had operated to keep the Western troops on the Ohio line, and the Unionists of West Virginia found a protecting military force at once in their immediate vicinity, with a commanding officer who was instructed to give them every encouragement and support.

Meanwhile, Governor Letcher, of Virginia, ignoring the attitude assumed by the people of the West, had issued his proclamation calling for the organization of the state militia, and including Western Virginia in the call. Prompted by a spirit of arrogance or over-confidence, he at an early day dispatched officers to that locality to collect and organize the militia of Western Virginia. Owing to the sparsity of the population, and the hilly and mountainous situation of the country, there were but two principal localities or lines of travel, where a concentration of forces could be best effected—one of these being the line of the Baltimore and Ohio Railroad, and the other the valley of the Great Kanawha river. In these districts Governor Letcher sent his recruiting agents, but they soon returned reports of a very discouraging character. The rebel emissaries found the feeling very bitter: that Union organizations existed in most of the counties, and that while fragments of rebel companies were here and there springing up, it was very evident that no local force sufficient to hold the country, would respond to the Confederate appeal, while the close proximity of Union forces at several points along the Ohio, pointed to a short tenure of Confederate authority.

This information was not at all cheering to the rebel Governor of the State, and he determined to maintain his authority in the disaffected districts with armed forces from the eastern portion of the State. To accomplish this, he detailed a few available companies from Staunton to march toward Beverly, from which point they could menace and overawe the town of Grafton, the junction of the main stem of the Baltimore and Ohio Railroad, with its branches extending to Parkersburg and Wheeling. The inhabitants showed more alacrity, however, to take up arms for the government than for Governor Letcher or General Lee. A Union Western Virginia regiment, under the command of Colonel Kelley, began to gather recruits rapidly at Wheeling, while the rebel camps between Beverly and Grafton were comparatively deserted, and Colonel Porterfield, who had been sent under orders of Governor Letcher, found his efforts at recruiting decidedly unsuccessful.

On the 23rd day of May the State voted upon the ordinance of secession, and East Virginia, under complete military domination, accepted the ordinance, while West Virginia, comparatively free, voted to reject the idea of secession.

Immediately after the result was ascertained, the rebel troops became aggressive, and Colonel Porterfield dispatched several of his companies to burn the bridge on the Baltimore & Ohio Railroad.

The appearance of these troops was quickly brought to the notice of the Federal authorities at Washington. On the 24th day of May the Secretary of War and General Scott telegraphed this information to General McClellan, and inquired "whether its influence could not be counteracted." General McClellan at once replied in the affirmative, and this was the sole order he received from Washington regarding a campaign in Virginia.

On the 26th, the General ordered two regiments to cross the river at Wheeling, and two others at Parkersburg. They were to move forward simultaneously by the branch railroads from each of these points to their junction at Grafton. The burnt bridges were restored in their passage, and after a most brilliant strategic movement, Porterfield was completely surprised, and the rebels were forced to disperse, in utter rout and confusion.

This complete success of the first dash at the enemy had the most inspiriting effect upon the Union troops, and also encouraged and fortified the Western Virginia unionists, in their determination to break away from the East and to form a new State. This movement was successfully accomplished, and early in July they elected two United States senators, who were admitted to, and took part in the national legislature.
