Rochester Public library has scanned a 3 volume set called “New York in the Spanish-American War.” This set is a report of the NY State Adjutant-General and was published in 1900. It gives a list of NY State Regiments that participated in the war and then gives a list of men in that unit noting when and where they mustered in and mustered out.
My grandmother’s brother George Webster served during the war. He went to the Philippines and after the war was over he stayed in Manila as a policeman for over a year. I even have a photo of him in his police uniform. Still, I wasn’t able to find him listed in these volumes.
The Spanish-American War was very short only taking place in the year 1898. The US got into the war after the sinking of the USS Maine that also resulting in the loss of 266 US sailors. As a result of the peace treaty Spain relinquished sovereignty over Cuba, ceded the Philippines, Puerto Rico, and Guam to the US. Cuba became independent in 1902 but the US got a perpetual lease of a military base in Guantanamo Bay.
