Around the time of the American Civil War the land military (that is the Army) had its sympathies on the cause of the Confederacy, in my opinion, due to the make up of the military officers of the time being mostly from the American South. Many of the leaders and military commanders were from Southern states and their sympathies tended to be towards their home states. The US Navy around the same time must have had an officer core that came in a majority from somewhere, but I've not seen any written materials that have investigated this.
What was the composition of the US Navy around this time? Were they in a majority from Northern states that already had a naval culture? Granted the US Navy was relatively small at this time but those people had to come from somewhere and I am interested in knowing where to sort of gauge where their sympathies might have lie.
