General — Deeming it of vital importance, for a time, Yorktown, on York river, and Mulberry Island on James river, and to keep the enemy in check by an intervening line, until the authorities might take such steps as should be deemed necessary to meet a serious advance of the enemy in the Peninsula, I felt compelled to dispose my forces ining forces along the Warwick line, embracing a front from Yorktown to Minor's farm of twelve miles, and from the latter place to Mulberry Island Point of one and a half miles.
I was compelled to place in Gloucester Point, Yorktown, and Mulberry Island, fixed garrisons amounting to six thousand men, my whole force being eleven thousand (11,000,; so that it will be seen that the balance of the line, embracing a length of thirteen miles, was defended by about five thousand men.
