Rank insignia of a CSMC captain

The Colonel-Commandant of the CSMC, Lloyd J. Beall, said the CSMC "was composed of enlisted men, many of whom were old soldiers and commissioned officers, a number of whom had seen service before in the U.S. Marine Corps and elsewhere."^[4] The record of US Marine officers who "resigned and tendered their swords to the Confederate Government"^[2] were:

These officers assembled with the CSMC as it stood up in Richmond, Virginia, with the exception of Captain Tansill, who had resigned while still on board USS Congress at sea. Captain Tansill was arrested by order of Secretary Welles of the U.S. Navy when he arrived in New York on August 23, 1861, and was held without charge, hearing or trial. He was released on January 10, 1862, as part of a prisoner exchange, and subsequently joined the CSMC in Virginia. "The gross injustice done him was recognized in an act of the Confederate Congress of April 11, 1863, which provided that 'officers of the navy and Marine Corps who resigned from the navy and Marine Corps of the United States in consequence of secession, and who were arrested and imprisoned in consequence of such resignation, and who subsequently joined the navy and Marine Corps of the Confederate States,' should receive 'leave of absence, pay for and during the term of such imprisonment, and up to the time of their appointment in the navy and marine corps of the Confederate States.'"^[5]

Manpower composition

The breakdown of officer manpower composition was:

• One colonel-commandant
• One lieutenant colonel
• Three majors (a quartermaster, paymaster, and an adjutant)
• Ten captains
• Ten first lieutenants
• Twenty second lieutenants

The breakdown of enlisted manpower composition as of Sep 24, 1862 was:

• One sergeant major
• One quartermaster sergeant
• Sixty sergeants
• Sixty corporals
• 840 privates
• Thirty drummers
• Thirty fifers
• Two principal musicians and two musicians

Although the CSMC had an authorized manpower of 1,026 men, its enrollment never approached that number; the figures for October 30, 1864 list only 539 officers and enlisted men.^[6] Though the officers were mostly former U.S. Marine officers, the head of the corps, Colonel-Commandant Lloyd J. Beall, was a former U.S. Army paymaster with no Marine experience. Major Lloyd J. Beall, USA graduated from the United States Military Academy, and had served in the First Infantry and Second Dragoons before becoming a paymaster from 1844 until the outbreak of the war. He resigned his commission on April 22, 1861, and was appointed Colonel-Commandant of the CS Marine Corps on May 23, 1861. Colonel Beall served throughout the war as the only Commandant of the Marine Corps.^[4]

Unit organizations

The C.S. Marine Corps was organized into several lettered companies and numerous shore-based and shipboard detachments. Companies A, B, and C were originally formed between April 10 and June 29, 1861, at New Orleans, LA. Company D, initially recruited in Memphis, Tennessee and Mobile, Alabama (August - September 1861) served in Pensacola, FL before being disbanded there and reformed at Mobile in November, 1861. Company E was formed at Savannah, Georgia in July 1862. There was also a Company F, initially formed at New Orleans in the spring of 1861, where it served for a brief period before being disbanded; it was later reformed at Mobile in April 1863 and disbanded for the second time in June 1864.

Companies A, B, and C were individually transferred from New Orleans to Pensacola from April through June 1861. Company A was subsequently transferred to Savannah in September 1862 before being transferred to Camp Beall, Virginia, to join Companies B and C, already there. Company B was briefly transferred to Mobile in February 1862 before being transferred to Camp Beall a few weeks later to join Company C, which had already been transferred there in November, 1861 to form the nucleus of what would become the organization (with the addition of Companies A and B) known as the "field battalion."

The battalion served in the defense of Richmond against riverine attack, provided ship's detachments to warships based in the Norfolk area, and participated in the general Confederate retreat from Richmond, performing notable combat action in the rear guard of General Lee's army as the Marine Battalion of Brigadier General (formerly Rear Admiral and commander of the Charleston Squadron, CSN) John R. Tucker's Naval Brigade at the Battle of Saylor's Creek (Virginia) on April 6, 1865. The majority of the battalion surrendered at Saylor's Creek on April 7, 1865, with most of the remainder surrendering with the Army of Northern Virginia on April 9, 1865, at Appomattox, Virginia.

Company D, initially stationed in Pensacola was disbanded in December, 1861 after being used to fill-out Companies B and C, also serving at that station. Company D was reformed at Mobile and served there, where it remained until that city fell to U.S. forces. Company D was the last organized unit of the CSMC to surrender; elements of the company surrendered on May 9, 1865, at Citronelle, Alabama and the remaining platoon, under the command of 1st Lieutenant David G. Raney Jr., surrendered at Nanna Hubba Bluff, Alabama on May 10, 1865.

Company E, initially formed in Savannah, subsequently evacuated to Charleston, South Carolina. A detachment of the company was sent to Wilmington, NC and participated in the unsuccessful defense of Fort Fisher. The remainder of Company E, still at Charleston, ultimately evacuated to North Carolina and joined with General Joseph E. Johnston's Army of Tennessee near Raleigh, North Carolina and surrendered with Brigadier General (formerly Rear Admiral and commander of the James River Squadron, CSN) Raphael Semmes's Naval Brigade at Greensboro, North Carolina on April 28, 1865.

Company F served originally at New Orleans as a "depot" company (i.e., recruiting and training unit) before being disbanded. It was later reformed at Mobile, again as a depot company, supplying Marines for Company D and the battalion at Camp Beall, eventually being disbanded for the final time in June 1864.

CS Marine Corps units were stationed at Confederate naval bases, as well as helping garrison shore fortifications such as Fort Fisher in North Carolina. Marines also served on Confederate warships. In the famous battle between the ironclads USS Monitor and CSS Virginia, Company C, Confederate States Marine Corps, served aboard CSS Virginia, helping to man several of her guns.

In the summer of 1862, some CS Marine Corps troops were organized into squad-sized units and dispersed throughout the south.^[3] Dispersed Marine units were intended to provide training to overcome a shortage of trained naval gunners, with greater overall effect than their service as a single naval artillery battalion.^[3] With detachments spread at every major Confederate naval installation, Headquarters for the Confederate States Marines was established at Fort Darling and Camp Beall, located at Drewry's Bluff on the James River in Virginia. As described above, three companies (A, B, and C) were stationed semi-permanently as the "field battalion" at CSMC headquarters. New CSMC officers were trained in the battalion prior to assignment to one of the detached companies (viz., D or E) or directly to one of the shore-based or shipboard Marine detachments. The "field battalion" Marines helped repulse the attack made on the bluff by U.S. naval forces including USS Monitor and USS Galena in the summer of 1862.

Despite desertions and even near-mutinies, most Marines served competently and deserved Navy Secretary Stephen R. Mallory's praise for their "promptness and efficiency." The corps' weakness was due largely to internal squabbles over rank, shore duty, and administrative assignments. Also, with no funds for bounties, the corps could not easily enlist recruits. Until 1864 the monthly pay of enlisted men was $3 less than that of equivalent army grades. Only late in the war were the Marines allowed to draw from army conscripts to augment their ranks.^[7]
