The Republic of Cuba (6)

The Columbia Barracks postal station, located in the suburbs of Havana, was established on February 18, 1899, and was the successor to United States Military Postal Station No. 10. It was operated under U.S. military authority until noon on May 20, 1902, when the office was turned over to Cuban postal authorities.

Apparently activated again as a military post during the North American military intervention of 1906, this cover was posted by the Chief Colonel of Regiment No. 1 stationed there, on July 29, 1909.
