Whoever, without a vast preponderance of forces, makes war to capture Richmond, must have the James River for his base of supply and must be able to control Harrison Landing.
When the campaign of the Army of the Potomac began, the iron-clad Merrimac barred access to the James, and the Army, which by way of that River might, without delay or loss, have flanked Magruder back to Malvern Hill, landed at Harrison’s and operated on Richmond over a healthy and dry country, comparatively free from natural obstacles,--was compelled to resort to the narrow and tortuous Pamunkey, and to flounder among swamps and river crossings, always exposed to fight at disadvantage, and always weakened physically and mentally by the malaria of the marshes.
When, by the destruction of the Merrimac, the James was made available, the mind of General McClellan reverted to his original preference. For a long time he waited and stretched out his right wing to facilitate junction with McDowell, but when the last hope of that aid had disappeared, he hastened to abandon the Pamunkey for the broader and safer James. The movement was actually in progress when Johnston attacked what was already the rear of McClellan’s column. During each day of that battle-week, the trains moved and the army fought, and every night the army abandoned the scene of a successful defence to close in upon the banks of the river, where alone they could hope for the supplies which they needed and the repose they had won.
The day before we joined, these rough and grimy troops had fought at Malvern perhaps the hardest of their fights, and had won the most complete of all their victories. And now they were again in communication with the North--in possessions of the very key to Richmond--holding Lee as it were by a cord from any movement North, and needing only the assistance of a tithe of the new levies to drive or flank him further south. But it pleased God that this should not be until years had passed away.
If there be on the face of the earth a place intended for breeding pestilence, the country about Harrison’s and Westover was ordained to that use. One of our officers who had travelled the wide world all over, declared that the climate resembled no place except Sierra Leone on the African coast. Its reputation as an unwholesome spot is established even among the natives of Virginia, and whoever desires any additional testimony, need only to apply to one who has sweltered there through July and August.
