The 5th we marched nine miles through deep mud and rain to the battlefield in front of Williamsburg, the last four and a half on the double quick and a run. The men, exhausted, in profuse perspiration, and wet to the skin, were obliged to lie on their arms during the night without either blankets or fires. From that hour the sickness of the regiment increased frightfully, six or eight new cases occurring daily. We left twenty-seven men in hospital at Williamsburg, sent six to transports at West Point when opposite that place, sent sixty away at Cumberland Landing, left forty-eight at Baltimore Store, and had sixty-four on the sick list at Bottom's Bridge on the 31st of May.

At the battle of Fair Oaks, on the last day of May, we lost of men and officers eleven killed and forty-nine wounded. Of the last, twenty-three were wounds of the upper extremities, two requiring amputation of the arm, and one exsection of the elbow joints; twelve of the lower extremities, four of thigh, seven of leg, and one of knee joint, eight of trunk (three serious); six of head (one serious), and two of both upper and lower extremities.

While at Fair Oaks from the 1st to the 29th of June, the regiment suffered greatly from fever and dysentery, the first of miastamic origin, which, together with the effect of constant apprehension, rendered the nervous system highly impressible. Hence the marked effect of the malaria upon the nervous centers, especially the spine, as evidenced by the almost constantly present—to a greater or less degree—numbing of the extremities with partial paralysis of the lower, usually severe pain in the hips and lumbar region, with great depression of spirits, etc.

The diarrhoea, as well as all diseases resulting from bad digestion or affections of the digestive organs, were caused mainly, if not entirely, by improper habits of cooking and eating. Each soldier cooked for himself, having no other implements than a small tin pail made from fruit can, a tin cup and a borrowed frying pan. Every leisure moment was devoted to cooking and eating; meat of every description was fried instead of being boiled. All regularity in eating was lost, except that uncertain kind, produced by relief from the routine of duty. Nor can any remedy be suggested short of the entire removal of the cooking business from the hands of the soldier, and placing it in charge of a competent corps organized for that special purpose. Soldiers cannot march and fight each with a complete stock of cooking furniture on his back.

In an active campaign like that on the Peninsula, officers suffer from bad cooking equally with the men. Servants are an uncertain kind of dependencies and often obliged to cook for himself, the officer is of course as unskilled as the soldier. A regimental mess for the officers of this regiment under charge of a competent cook, established a few weeks ago, has already proved decidedly advantageous. A similar arrangement for the men, for instance by companies, would be found to be as great an improvement.

For five days before commencing the retreat from before Richmond to Harrison's Landing our men were almost constantly on duty. On the 29th of June they skirmished all day, then marched half of the night. The next day (30th) they fought at Charles City Cross Roads, losing seven killed and fifty-six wounded, most of whom fell into the hands of the enemy. They watched until two o'clock a. m., July 1st, then marched to Malvern Hill, fought there, losing two killed and eight wounded; remained on picket until 9 a. m. next morning, then marched twelve miles through deep mud and hard rain to Harrison's Landing, camped at night in the mud, then moved three miles and camped permanently for outpost duty.

All were exhausted and disheartened, scarcely a well man in the regiment, two hundred and thirty on the sick list for the first few days. Scurvy made its appearance to a small extent, yet sufficient to complicate and multiply other ailments. However, a few weeks' rest, abundance of fresh vegetables, lemons and ice, and we were ready to commence the retreat from the Peninsula with two hundred and fifty men for duty, having lost four by death at Harrison's Landing—two by typhoid fever, one from entraperitonitis and one from phthisis pulmonalis.

On reaching Alexandria we immediately moved to the Rappahannock, had no sickness of moment except two cases of sunstroke, being actively engaged, yet not overworked.

We had three wounded at Bull Run, one in the hand, one in the hip, and one in the breast and face. These last two have since died.

The present health of the regiment is good and its moral condition excellent.
