A surprise attack and spectacular landing

The Cold War escalated when communist North Korea invaded South Korea in what was seen as a global military challenge. As the head of UN forces, Army General Douglas MacArthur relied on the amphibious capabilities of the Marine Corps to reclaim South Korea's occupied capital, Seoul. 
 
In a surprise attack, Marines landed behind enemy lines on the heavily defended shores of Inchon. Moving from landing ship tanks, they climbed the seawall with gunfire support from helicopters above.  
 
Within hours, the Marines cleared the beach and began moving toward Seoul. In two weeks, they reclaimed the capital and put the North Korean army on the run.  
 
More than a battle victory, the landing at Inchon is considered one of the most spectacular amphibious assaults in history. The planning and landing became the model for the Marine Corps’ Operational Maneuver from the Sea strategy.
