and would have been better rested and more physically fit. The lack of food was a serious problem for the Army of Northern Virginia, as most crops were a month away from harvesting in September and many soldiers were forced to subsist on field corn and green apples, which gave them indigestion and diarrhea. As noted above, malnutrition was greatest in the two divisions of Jackson's old Valley Army due to months of unbroken fighting and marching. Initial movements On September 3, just two days after the Battle of Chantilly, Lee wrote to President Davis that he had decided to cross into Maryland unless the president objected. On the same day, Lee began shifting his army north and west from Chantilly towards Leesburg, Virginia. On September 4, advance elements of the Army of Northern Virginia crossed into Maryland from Loudoun County. The main body of the army advanced into Frederick, Maryland, on September 7. The 55,000-man army had been reinforced by troops who had been defending Richmond—the divisions of Maj. Gens. D.H. Hill and Lafayette McLaws and two brigades under Brig. Gen. John G.

Davis wrote to explain to the public (and, indirectly, the European Powers) why the South seemed to be changing its strategy. Until this point, the Confederacy had claimed it was the victim of aggression and was merely defending itself against "foreign invasion."

"We are driven to protect our own country by transferring the seat of war to that of an enemy who pursues us with a relentless and apparently aimless hostility." Davis's draft proclamation did not reach his generals until after they had issued proclamations of their own. They stressed that they had come as liberators, not conquerors, to these border states, but they did not address the
