Seeking award information & USS Threadfin

My submarine the USS THREADFIN SS 410 was involved in a clandestine operation under direct orders from the President of the United States during the Cuban missile crisis. I just found out that we were awarded the "Combat Action Ribbon" for said mission. Can you elaborate on this for me since I was onboard at the time. I am confident this information is correct since a letter was received by the SecNav at the time and seen by others.
