The two Rhode Island, the 71st New York, and the 2d New Hampshire, comprising Colonel Burnside's brigade, left Washington at 4 o'clock this afternoon, and struck the road for Fairfax Court House. The 27th New York went over at 5 o'clock, and also took the Fairfax -IN the Senate of the United States, John C. Breckenridge, of Kentucky, in an elaborate speech, opposed the resolution approving the acts of the President in suppressing the Southern rebellion. He rehearsed the old arguments against the right of the Government to put down rebellion, and in the course of his re-route. As soon as these regiments came tomarks, took occasion to deny positively that ho had ever telegraphed to Jeff. Davis that President Lincoln's Congress would not be allowed to meet in Washington on the 4th of July, or that Kentucky would furnish 7,000 armed men for the rebel army.-(Doc. 94.) gether and passed the encampment, the soldiers cheered lustily and shouted congratulations to each other that they were fairly on the road to the rebel capital. The Dekalb Regiment passed over the bridge and went into Camp Runyon.-(Doc. 97.) July 17.-The advance column of the National army occupied Fairfax Court House, Va., at eleven o'clock to-day, meeting with no opposition from tho Confederates either on the march or in taking possession of the place. Trees had been felled across the road and preparations made at one point for a battery, but there were no guns or troops on the route. The Confederates were drawn up beyond the town and a battle was expected, but as the National forces pressed on they retreated. The cavalry followed them some miles toward Centreville, but the heat of the weather and the previous long march prevented the infantry following. The abandonment of the village by the Confederates was so sudden that they left behind them some portions of their provisions, intrenching tools, and camp furniture. The army advances in three columns, one on the Fairfax road, and the others to the north and south of the road. The advance will be continued to Centreville, eight miles beyond Fair -IT is doubtful, says the National Intelligencer of this date, whether, since the days of Peter the Hermit, the world has seen such ar uprising, at the bidding of a sentiment, as this country has exbibited in the last ninety days. Perhaps the magnitude of the effort is best appreciated by observing what has been done by single States of the Confederacy. And to illustrate this, we need not even adduce the exertions of sovereignties dating back to Revolutionary days, as New York, Pennsylvania. and Massachusetts. Younger members of the Confederacy, States that half a century since had no existence, contribute singly no inconsiderable army to the assembling forces of the Union. Let us instance one of these, which recent events in Western Virginia have brought favorably and prominently forward-Indiana, forty-five years ago a frontier Territory, where the red man still contended with the white pioneer. | Indiana las equipped, and is equipping for the General Government, a force such as has decided ere now the fate of a nation-twenty-fax, where the Confederates will probably make three regiments, a volunteer army of more than twenty thousand infantry and twelve hundred cavalry; and these she has not only uniformed and accoutred, but partially armed with the improved rifle of the day, meanwhile at her own expense. This is no isolated example. Others have done as well. If the power of a sentiment is to be estimated by the deeds it prompts, how strong must be the love of the Union in the hearts of its citizens! -THE Federal army in Virginia to-day took up the line of march for Fairfax and Manassas. The force standing to-day is fully 50,000 strong, the number reaching by actual count about 58, a stand if they design attempting to hold Manassas Junction. The only casualties reported by Gen McDowell are an officer and three men slightly wounded.-(Doc. 98.) -THE Sixth Regiment of Maine volunteers, commanded by Colonel Abner Knowles, left Portland for the seat of war. The regiment, which has been recruited mainly from the counties of Washington and Penobscot, consists mostly of stout, hardy lumbermen, already inured to hard work and apparently ready for more. Many of the privates measure six feet four. They are uniformed in a similar manner to the other Maine regiments. Each man has an extra fatigue uniform, consisting of gray |
