Interesting list of all engagements on sea and land during the War of 1812. Note that pages 37-125 are specifically ship actions and list hundreds, perhaps thousands of incidents, mainly relating to the capture by RN or US privateers of trading vessels. The scope of the merchant losses is staggering. Enjoy!
