General Hooker, "Fighting Joe," with his division, maintained the contest for nine hours. Other troops at last arrived on the bloody field, and, Williamsburg having been evacuated in the night, the pursuit was continued to within seven miles of Richmond. _Richmond Threatened_.--There was a great panic in that city, and the Confederate Congress hastily adjourned. Everything looked like an immediate attack, when McClellan discovered that a Confederate force was at _Hanover Court House_. This threatened his communications by rail with White House Landing, and also with General McDowell, who, with thirty thousand men, was marching from Fredericksburg to join him. General Fitz John Porter, after a sharp skirmish, captured Hanover Court House. The army looked now hourly for McDowell's aid in the approaching great contest. "McClellan's last orders at night were that McDowell's signals were to be watched for and without delay reported to him" But General Johnston was too shrewd to permit this junction. He accordingly ordered General Jackson to move up the Shenandoah Valley and threaten Washington. _Jackson in the Shenandoah._--Stonewall Jackson having been reinforced by General Ewell's division of ten thousand men, hurried down the valley after Banks at Strasburg. The Union troops fell back, and by tremendous exertion--"marching thirty-five miles in a single day"--succeeded in escaping across the Potomac. Great was the consternation in Washington. The President took military possession of all the railroads. The governors of the Northern States were called upon to send militia for the defence of the capital. Fremont at Franklin, Banks at Harper's Ferry, and McDowell at Fredericksburg, were ordered to capture Jackson. It was high time for this dashing leader to be alarmed. He rapidly retreated, burning the bridges as he passed. Fremont brought him to bay at _Cross Keys_ (June 8), but was hurled off. Shields struck at him at _Port Republic_, the next day, but was driven back five miles, while Jackson made good his escape from the Shenandoah Valley, having burned the bridges behind him. [Footnote: When the Federal forces took possession of the bridge over the Shenandoah, Jackson and his staff were on the south side, his army being on the north side. It is said that "he rode toward the bridge, and rising in his stirrups, called sternly to the Federal officer commanding the artillery placed to sweep it: 'Who ordered you to post that gun there, sir? Bring it over here!'" The bewildered officer bowed, limbered up his piece, and prepared to move. Jackson and his staff seized the lucky moment and dashed across the bridge before the gun could be brought to bear upon them.] _The Effect_ of this adroit movement was evident. With fifteen thousand men, Jackson had occupied the attention of three major-generals and sixty thousand men, prevented McDowell's junction, alarmed Washington, and saved Richmond.
