Colombian liberals had seized the town of Colón, Panama and the Panama Railroad and appeared ready to take Panama City. "Concord" arrived on November 23 and Lieutenant-Commander Minett was placed in command of a battalion of 412 men from the two ships. To reclaim the railroad, Minett launched trains under guard from Panama City, each sporting two American flags. If the Colombian liberals fired on the trains, the Navy would consider this serious enough provocation to reply in force. In this way, the railroad was restored with no major conflicts.

Colón was surrendered to the US Navy on November 30 and the Navy pulled out its ships shortly after.
