Although the 1st Provisional Marine Brigade disbanded shortly after, the MCA remained active. Two years later, again at Guantanamo Bay, officers of the 2d Provisional Marine Brigade, commanded by Colonel Lincoln Karmany, formally organized the Marine Corps Association. Colonel Karmany appointed then-Lt. Colonel John A. Lejeune as its first head of the executive board. After returning to the United States, Lejeune was again called upon for expeditionary duty. He sailed from Philadelphia, 20 February 1913 as second in command of the First Regiment, Second Provisional Brigade Marines and disembarked 27 February 1913, at Guantanamo Bay, Cuba. Then-Lt. Colonel Lejeune became the first head of the Marine Corps Association with the goal of professional advancement among Marines. He returned to Philadelphia on board USS "Prairie" on 2 May 1913.
