There is nothing more definite or authentic from Winchester, except that we certainly captured Milroy’s army of not less than 5000 men.

To-day the government issued musket and ball-cartridges (forty to each) to the volunteer companies raised in the departments for home defense. If this does not signify apprehension of an immediate attack, it proves at all events that Lee’s army is not to be around the city as it was a year ago—and that signifies his purpose to advance.

June 20th.—It has got out that the President intends to dispense with the services of Mr. Myers, the Jew Quartermaster-General, and Mr. Miles, member of Congress from South Carolina, who happens to be his friend, is characteristically doing the part of a friend for his retention. But he gives the President some severe raps for alleged contempt of the wishes of Congress, that body having passed a bill (vetoed by the President) conferring on Col. M. the rank and pay of brigadier-general.

The operations of Gen. Lee have relieved the depot here, which was nearly empty. Since the capture of Winchester and Martinsburg, only about 1500 bushels of corn are sent to the army daily, whereas 5000 were sent before, and there were rarely more than a day’s supply on hand.

To-day, about one o’clock, the city was thrown into a state of joyful excitement, by the reception of news from the North. From this source it was ascertained, what had hitherto been only a matter of conjecture, that a portion of our forces, the same that captured Winchester and Martinsburg, were in Pennsylvania! Gen. Jenkins, with his cavalry, had taken Chambersburg on the 16th inst.—and the North, from the line of Pennsylvania to the lakes, and from the seaboard to the western prairies, was stricken with consternation. These are some of the dispatches, as copied from Northern papers:

“The Governor of Ohio calls for 30,000 troops. The Governor of Pennsylvania calls for 50,000, to prevent the invasion of each State.

“Washington, June 15th.—Lincoln has issued a proclamation for 100,000 men, to repel the invasion of Maryland, Northern Virginia, Pennsylvania, and Ohio.

“Harrisburg, June 15th.—Dispatches from Chambersburg and Hagerstown state that the rebel cavalry are at Berryville and Martinsburg. A dispatch dated 14th, says that hard fighting is going on. The rebels had driven Reynolds from Berryville, and were advancing on the capital. The towns and cities throughout Pennsylvania are in danger.

“Later.—Private dispatches state that on the 16th the rebels were at Chambersburg in force. The Federals were removing the railroad machinery, stock, and stores. Great excitement and alarm pervaded the entire country.”

In the “hard fighting,” Gen. Lee reports our loss as “one killed and two wounded.” Here’s the second dispatch:
