It was a history-making strike that involved the most formidable cruiser/destroyer fleet in the Western Pacific since World War II.

During the strike, military targets within four miles of Haiphong were hit and enemy opposition was heavy.

During the raid, USS Hanson entered Haiphong Harbor to suppress North Vietnamese shore batteries while enabling other United States Navy forces to mine the Haiphong Harbor entrance.

This made USS Hanson the last American warship to enter Haiphong Harbor during the Vietnam War and the last one out.
