The lineage of the modern 2nd Marine Regiment traces from its activation as the 1st Advance Base Regiment at the Philadelphia Naval Shipyard on 19 June 1913. The following year that designation was changed to 1st Regiment, Advanced Base Force. That unit landed as part of a joint force to secure and occupy the Mexican port of Veracruz in 1914. That brief encounter resulted in two Medal of Honor (MOH) awards to members of the regiment, Wendell C. Neville and Smedley D. Butler. The following year, the regiment was posted to Cap Hatien, Haiti, to safeguard American lives and property. This turned into a long occupation during which the regiment carried put extensive patrolling, engaged in numerous sharp firefights, and trained a native constabulary. The most notable single action was the reduction of Fort Riviere, the most notorious rebel stronghold. Smedley Butler and Daniel Daly were both awarded their second Medals of Honor for valorous actions in Haiti. In 1916, the unit was redesignated 2nd Regiment, 1st Brigade. In 1933, the 2nd Regiment was redesignated the "2nd Marines." The following year, the 2nd Marines departed Haiti then was disestablished on 15 August 1934.
