21st—Occasional firing between the batteries on Warwick Creek to-day, without results worth noting. Sickness among the troops rapidly increasing. Remittent fever, diarrhœa, and dysentery prevail. We are encamped in low, wet ground, and the heavy rains keep much of it overflowed. I fear that if we remain here long we shall lose many men by sickness.
This neck of land, between Yorktown and Jamestown, it seems now is to be made the point d’appui of the armies in Virginia. If we can, and will break up this army, it will put an end to the war, and until this army is overcome or dispersed, be it a month or a year, there will be no progress in the direction of a satisfactory peace. We are getting forward our siege guns, concentrating forces, in a word, preparing for battle. My request to be relieved of the Brigade Surgeonship is to-day granted, and I return to the charge of my regiment.
