l consideration, determined to cross the Potomac. The
movement was made with the same speed which had characterised the
operations against Pope. It was of the utmost importance that the
passage of the river should be accomplished before the enemy had time
to discover the design and to bar the way. Stuart's cavalry formed
the screen. On the morning after the battle of Chantilly, Fitzhugh
Lee's brigade followed the retreating Federals in the direction of
Alexandria. Hampton's brigade was pushed forward to Dranesville by
way of Hunter's Mill. Robertson's brigade made a strong demonstration
towards Washington, and Munford, with the 2nd Virginia, cleared out a
Federal detachment which occupied Leesburg. Behind the cavalry the
army marched unmolested and unobserved.1

D.H. Hill's division was pushed forward as advanced guard; Jackson's
troops, who had been granted a day's rest, brought up the rear, and
on the morning of the 6th reached White's Ford on the Potomac.
Through the silver reaches of the great river the long columns of men

water, wound steadily northward over the green fields of Maryland.

(1 The Army of Northern Virginia was thus organised during the
Maryland campaign:--

Longstreet's McLaws' Division = 35,600
R.H. Anderson's Division
D.R. Jones' Division
J.G. Walker's Division
Evans' Brigade
Washington Artillery
S.D. Lee's Artillery battalion

Jackson's Ewell's (Lawton) Division = 16,800
The Light (A.P. Hill) Division
Jackson's own (J.R. Jones) Division

D.H. Hill's Division = 7,000

Pendleton's Reserve Artillery, 4 battalions = 1,000

Stuart Hampton's Brigade = 4,000
Fitzhugh Lee's Brigade
Robertson's Brigade
3 H.A. Batteries, Captain Pelham

Total 64,400

No allowance has been made for straggling. It is doubtful if more
than 55,000 men entered Maryland.)

September 7.

The next day Frederick was occupied by Jackson, who was once more in
advance; the cavalry at Urbanna watched the roads to Washington, and
every city in the North was roused by the tidings that the grey
