5th U.S. Cavalry at Gaines Mill – Casualties

The official casualty count of the regiment in the battle was 1 officer and 3 enlisted men killed in action, 3 officers and 27 enlisted men wounded in action, and 2 officers and 19 enlisted men captured or missing in action, for a total of 55 casualties. (OR, Vol. 11, pt. 2, pg. 40)

To the best of my knowledge, no one has listed the names of the casualties, so it seems appropriate to do so for the 150th anniversary of the battle.

The regimental muster rolls for June 1862 reflect the following casualties in the battle. Some of the names could be misspelled, as they are very difficult to read on the return, and I haven’t yet been able to verify them through CWSS or their enlistment documents.

The monthly return for June 1862 states a total of 58 missing in action for the regiment for the month. 30 of these were lost at Old Church on the 13th, presumed captured on picket.

There is a discrepancy between the number of wounded enlisted men listed by company on the first page of the return and the names listed on the second page. The numbers of Companies A, D and F match. Company H lists 9 wounded but 10 names wounded in action. Company I lists 4 wounded but only two names.

Listed strength of the companies present for duty listed above in the muster rolls for the end of June 1862:

Co. A: 1 officer, 45 enlisted men
Co. D: 32 enlisted men
Co. F: 1 officer, 44 enlisted men
Co. H: 26 enlisted men
Co. I: 47 enlisted men

The regiment’s mounts suffered in the fight as well. Company A lost no horses, but had 17 unserviceable mounts at the end of the month. Company D lost 29 horses. Company F lost 20 horses, and an additional 4 were unserviceable at the end of the month. Company H lost 18 horses, with an additional mount unserviceable at the end of the month. Company I lost 9 horses, with 4 additional horses unserviceable at the end of the month.

5th U.S. Cavalry at Gaines Mill – Official Regimental Report

Report of Capt. Joseph H. McArthur, Fifth U.S. Cavalry, of battle of Gaines’ Mill.
“Headquarters Fifth U.S. Cavalry
In the Field, July 3, 1862.

Sir: Agreeably to instructions I have the honor to make the following report of the operations of the Fifth U.S. Cavalry in the battle which occurred on Thursday, the 27th of June, 1862, near Woodbury’s Bridge, on the Chickahominy:

It is here proper to state that there were but five companies present, the remaining five acting with General Stoneman to the right and rear.

During the first part of the engagement the regiment was kept out of fire, prepared to move wherever occasion demanded. Late in the action, and about 6 o’clock in the afternoon, the regiment was moved up and formed in line of battle to support Benson’s battery and another battery on the right. The regiment occupied this position until the battery on the right had ceased firing. The enemy advanced boldly on these batteries, which had opened a murderous fire upon them with the evident intention of carrying them. As soon as the battery on our right ceased firing Captain Whiting, who was at that time in command, gave the order to charge. The regiment charged the enemy’s infantry under a most galling fire until 6 officers out of 7 had been struck down. The column, being left without officers, wheeled to the right, and came off in as good order as could be expected.

I regret to state that Captains Whiting and Chambliss and Lieutenant Sweet have not been seen or heard of since the charge, and I am unable to state whether they are killed or merely wounded and taken prisoners.

Great credit is due to Adjt. Thomas E. Maley, who, although severely wounded, rendered great service to me in assisting to reform the regiment at once in rear of our forces. Lieutenant Watkins was severely wounded and also trampled on by several horses of the regiment. Lieutenant Arnold was slightly wounded.
I am, sir, very respectfully, your obedient servant,

J. H. McArthur
Captain, Fifth Cavalry, Commanding Regiment.
Lieut. James P. Martin.
Acting Assistant Adjutant-General, Cavalry Reserve.

Note -- Those struck down were Captains Whiting and Chambliss, Lieutenants Arnold, Sweet, Watkins and Maley, leaving Capt. J. H. McArthur alone unhurt and in command of the five companies of the regiment engaged.

J. H. McArthur
Captain, Fifth Cavalry, Commanding.”

1st U.S. Cavalry at Gaines Mill, 27 June 1862

For the regular cavalry, the battle of Gaines Mill is best known for the charge ordered by Brig. Gen. Philip St. George Cooke at the end of the battle by the 5th U.S. Cavalry. Although the 1st U.S. Cavalry had a minor part to play in the larger drama of the battle, I felt that someone should tell their story as well.

Report of Lieut. Col. William N. Grier, First U.S. Cavalry, of battle of Gaines’ Mill.
“Headquarters First U.S. Cavalry
Camp near Richmond, Va., June 28, 1862.

Sir: For the information of Col. G. A. H. Blake, First Cavalry, commanding Second Brigade of Cavalry Reserve, I have the honor to make the following report of the part borne in the action of 27th of June, 1862, at or near Gaines’ Hill, on the Chickahominy, by two squadrons of the First U.S. Cavalry. The whole strength of the regiment on that day consisted of two small squadrons, about 125 enlisted men, Captain Reno, First Cavalry, commanding one squadron, and Lieutenant Kellogg commanding the other. During the day the regiment was kept moving from one point to another until in the afternoon it was placed, together with the Fifth U.S. Cavalry and Rush’s Lancers, (volunteer cavalry), on the extreme left, in the support of our artillery.

Late in the afternoon our left wing was driven back by very heavy re-enforcements of the enemy, and after they debouched from the timber in our front were charged by the Fifth Regiment of U.S. Cavalry, my two squadrons directed to be held as a reserve to watch the effect of that charge and act accordingly. The charge of the Fifth having made no visible impression on the overwhelming masses of the enemy and none of them effecting a rally on the reserve, my squadrons retired in good order at a walk in rear of our artillery.

During the afternoon’s engagement the squadrons were subjected to a heavy fire from the enemy, which was met with coolness and steadiness by officers and men. Colonel Blake having been present, and acted with these two small squadrons of the regiment, is fully cognizant of its services during the day, and therefore probably requires no detail of its different movements from point to point during the day.

Wm. N. Grier
Lieutenant-Colonel, First Cavalry, Commanding Regiment.

Lieut. N. W. Kneass,
Actg. Asst. Adjt. Gen., Second Brigade, Reserve Cavalry.” (OR, Vol. 11, pt. 2, pgs. 45-46)


From Lt. Col. Grier’s report, it sounds as though the 1st U.S. Cavalry had a pretty easy day of it, shifting from point to point on the battlefield, watching the charge of the 5th U.S. Cavalry, and never really engaged in the fighting.

Perhaps an examination of the brigade commander’s report will shed more light on the fighting:

“Report of Col. George A. H. Blake, First U.S. cavalry, commanding Second Brigade, of the battle of Gaines Mill.

Headquarters Second Cavalry Brigade
Camp, Harrison’s Landing, James River, Va., July 3, 1862

Sir: In compliance with orders from the headquarters cavalry division I have the honor to report the movements of this brigade on the 26th instant and its engagement with the enemy on the following day.

The brigade consisted of two small squadrons of the First U.S. Cavalry, commanded by Lieutenant-Colonel Grier, and the provost guard of the division, consisting of 39 men, under the command of Lieutenant Balk, Sixth U.S. Cavalry. On the 26th instant information was received of the approach of the enemy, who we were informed were seen upon the road to our rear. The brigade was immediately formed. About 12 o’clock m. we took up our line of march and reached Cold Harbor, where we remained for the night.

About 7 o’clock upon the following morning (June 27) the line of march was again resumed, and we proceeded to a point which was then occupied for the time by General F. J. Porter as his headquarters, on the road leading to No. 8 Bridge. The brigade was placed in position, and about 11 o’clock the engagement commenced. A short time after the brigade was moved to the left and rear of the house occupied by General F. J. Porter as his headquarters. Late in the evening, when our infantry retired before the overwhelming numbers of the enemy, the brigade was ordered upon the hill in rear of the Fifth U.S. Cavalry, with orders to act as a reserve to the Fifth U.S. Cavalry, who were ordered to charge the enemy, and, if successful, to take advantage of it and follow it up. The fire of the enemy was so destructive that a charge was not effected. The command fell back with the artillery in good order and occupied a position about 600 yards from our former position. We were again ordered to the front, and acted as a support to a body of infantry who had rallied at the bottom of the hill and were holding the enemy in check. When our artillery was posted on the hill in rear we were ordered to retire, so as to be out of his fire. We fell back a short distance and remained until 1 o’clock a.m. on the 28th instant, when the command retired across the Chickahominy, near Savage Station.

I am indebted to Lieutenant-Colonel Grier, Captain Reno, Captain Kellogg, Lieutenant Feilner, Lieutenant Allen (dangerously wounded), all of the First U.S. Cavalry; Lieutenant Balk, Sixth U.S. Cavalry, and Lieutenant Kneass, acting assistant adjutant-general Eighth Pennsylvania Volunteer Cavalry, for the prompt and cheerful assistance given me on the field. Lieutenant Balk and myself were slightly struck during the engagement, but not of sufficient importance to notice further.
A list of casualties will be furnished when received.
I am, sir, very respectfully, your obedient servant,

George A. H. Blake,
Colonel First Cavalry, Commanding Brigade.

Lieut. James P. Martin.” (OR, Vol. 11, pt. 2, pg. 44)


Colonel Blake’s report provides a bit more detail on the regiment’s actions, but not much indication of the severity of the fighting beyond mentioning the one officer wounded.

In actuality, the regiment’s casualties for the battle consisted of 4 enlisted men killed in action, 1 officer mortally wounded, 18 enlisted men wounded in action, and 2 enlisted men missing, for a total of 25. (OR, Vol. 11, pt. 2, pg. 40) 20% of the force engaged is normally considered heavy casualties, though it pales in comparison to the 5th Cavalry’s losses in the fight.

Lt. Col. Grier, an officer of great experience, probably has an understated writing style. This is refreshing given the hyperbole of many battle reports. His entry on the regimental muster rolls for June 1862 has only this to say of the battle:


“The Regiment consisting of 4 Companies (A, C, F & H) under the command of Lieut. Colonel Wm. N. Grier were engaged in the action of 27th of June at Gaines Mill Va., loss in killed wounded and missing – 1 officer and 23 enlisted men.”

The mortally wounded officer was 1st Lieutenant Robert Allen, Jr. The regiment’s July 1862 return lists him as “died of wounds received in action in the Battle of Gaines Mill, Va June 27, 1862.” The names of the enlisted men killed and wounded in action are not listed in the monthly returns, and I’m still looking for the 1862 annual return for the regiment.

For those curious about the rest of the regiment, Companies B, E, I and K were at Fortress Monroe during the battle. The other squadron, Cos. D and G, were fighting in New Mexico.

Gaines Mill week

In commemoration of the 150th anniversary of the battle of Gaines Mill on June 27, 1862, I'll be featuring posts on the regular cavalry's participation in the battle this week. I won't focus on the decision-making of Brig. Gen. Philip St. George Cooke, as that's been covered before and likely will be again this week elsewhere. I'll focus on the stories of the two regular regiments involved, the 1st and 5th U.S. Cavalry regiments. I've examined their official reports and monthly returns for information on the battle. Unfortunately, I'm away from home on a work trip for the next month, so I'm not able to provide Chaplain Gracey's account of the charge of the 5th U.S. Cavalry. He was present on the field with the 6th Pennsylvania Cavalry.
