"U.S.S. Maine Havana, Cuba
Dear Father,
I received your loving letter a few days ago and was pleased to hear from you. I would have written sooner but owing to us having to been ordered to sea so soon. I didn't have any chance. We are now in Havana Cuba. We arrived here yesterday after a five hour run around a place called Dry Tartogos a small Florida reef. We were out to sea when the orders came for us to proceed to proceed at once to Havana. We are the first American ship that has been here in six years. We are now cleared for action with every gun in the ship loaded and men stationed around the ship all night. We are also ready to land a battalion at any moment. By the looks of things now I think we will have some trouble before we leave. We steamed the whole length of Cuba and about every mile you can see puffs of smoke and the Spainards firing on the rebels. There are three German ships (?) loading. here was Old Moro Castle stands at the entrance of the harbor, there are thousands of Spanish inside you can see them all sitting on the walls at any time of the day. This is a landlocked harbor but I think we could get out of it all right although we are in a pretty dangerous position at the present time and we hardly know when we are safe. Well dear Father I will now have to close sending my best love and wishes to all and hoping that I may be alive to see you all again. I remain you loving son. Charles
