Which battle in the Korean War is described as a successful tactical retrograde for the Marines?

• A. Battle of Chungking
• B. Battle of Chosin
• C. Battle of Seoul
• D. Battle of Pusan Perimeter

Answer: (B)

A tactical retrograde is a controlled, fighting withdrawal designed to preserve your fighting capability while you disengage from a superior threat, so you can regroup and fight again later.

In the Chosin Reservoir campaign, Marines faced a far larger Chinese force in brutally cold weather and difficult terrain. They conducted a deliberate retreat from the Chosin area to Hungnam, fighting to extract their forces rather than allow encirclement or destruction. Despite the heavy pressure, they kept the bulk of their units intact, inflicted substantial casualties on the attackers, and set the stage to regroup and continue the war. That combination—withdrawal under fire that preserves combat power and achieves strategic momentum—exemplifies a successful tactical retrograde.

The other battles involve either advances or defensive stands rather than a planned withdrawal. Reclaiming Seoul was an offensive movement, not a retreat; the Pusan Perimeter was a defensive hold to stabilize the front, not a retrograde; and Chungking is not a Korean War battle on the Korean front.
