Counting Heads: the US Army in 1814

Recently I found an undated document in the James Madison Papers, hosted online by the Library of Congress. Compiled sometime in 1814, it is a big list of the combined strength of the US Regular Army in that year. From the presence of some 12-month Infantry Regiments on the list, combined with the absence of any of the Ohio 12-months Regiments, I would guess that it was made up sometime in Spring or Summer 1814.
