A unique/fun foreign port call closed to the U.S. for the past 57 years:
Havana, Cuba - I'm a newly reported ETSN out of Sub School to my WWII fleet-type Sub USS Cavalla (SSK-244) at NSB New London, summer 1955. Soon after reporting, sent TAD to Fleet Sonar School, Key West FL, for a 3-week Submarine Sonar Operators Course.
During the first week, our small class was advised that the school's assigned training ship USS TWEEDY (DE-532), would be making a RT weekend port call to Havana the next weekend, underway Fri PM return Sun PM, we were welcome to come along (4-hrs cruise each way).
Great liberty, 2 nights on the town, and toured the Morro Castle, and a tobacco plantation/cigar factory during the day. Stayed in a beautiful hotel/casino (that I learned decades later, was owned by
Lucky Luciano & his NY "family", and run by
Meyer Lansky)!

They sure treated us like royalty back then.
Meanwhile, unknown to us,
Fidel, Raul, Che and their merry band of 'Commie' rebels were scurrying around the mountains of Sierra Maestra, fomenting the revolution that occurred 3 years later!
