 With the advent of World War I , the United States expanded the Armed Forces , to include the United States Marine Corps .

The battalion 's first mission was to keep order in the island and once this was accomplished , it was reassigned . There were rumors that German agents were going to disrupt Mexican oil shipments to Texas . The battalion was sent to Texas to safeguard these shipments . 2 / 9 was disbanded after the war on April 25 , 1919 only to be reactivated in 1925 .

 On May 12 , 1975 , barely two weeks after the fall of Saigon , Khmer Rouge forces seized a U.S. flagged merchant ship , the SS Mayaguez in recognized international sea lanes claimed as territorial waters by Cambodia and removed its crew for questioning . The Khmer Rouge naval forces used abandoned US Navy " Swift Boats " in the seizure of the U.S. container ship . 
 Calling the seizure " piracy " , President Ford ordered a military response to retake the ship and its 39 @-@ man crew , mistakenly thought to be on Koh Tang Island . On May 13 , two A @-@ 7D Corsairs saw the 39 man crew board a fishing boat and saw people disembarking fishing boats at Koh Tang Island . They assumed that the Mayaguez crew was on the island . Elements of the 1st Battalion , 4th Marines , the 2nd Battalion , 4th Marines , and the 2nd Battalion , 9th Marines , were flown to an advanced staging of a joint US Task Force . On May 14 , the Marines from Company D , 1st Battalion , 4th Marines boarded the Mayaguez only to find it deserted and raised the American flag . A Thai fishing boat with a Thai crew and the 39 crew members of the SS Mayaguez which had been set free , approached the USS Wilson .

 2nd Battalion , 9th Marines landed on Koh Tang Island where the crew of the SS Mayaguez was believed to be held , they were unaware that the crew was already in American hands . The Marines and the CH @-@ 53 helicopters which transported them , were attacked by the Khmer Rouge with machine guns , mortars , and rocket propelled grenade launchers in what became known as the Battle of Koh Tang Island . When the battalion received word of the safe arrival of the Mayaguez crew on the USS Wilson the Marines planned their withdrawal once they received orders from the U.S. Joint Chiefs of Staff to that effect . After the last helicopter left , a head count showed that 3 Marines were left behind on the island . They were : PFC Gary Hall , LCpl . Joseph Hargrove , and Pvt Danny Marshall from E CO , 2nd Battalion , 9th Marines . The three Marines were captured by the Khmer Rouge within a few days , tortured , executed , and buried in a common , unmarked grave on Koh Tang Island . 
 The Mayagüez incident with the Khmer Rouge , which ended on May 15 , 1975 , marked the last official battle of the 2nd Battalion , 9th Marines in the Vietnam War . The unit deployment program was put into practice in February 1979 , and 2nd Battalion , 9th Marines became the first battalion to rotate to the United States . A total of 18 Marines were killed on the last day of the SS Mayaguez rescue operation .
