RNMCSA, sir;

I would like to add the following possibilities and perhaps when looking at military coats open, will support my opinions.
e) Access to the vest pocket, as to get to the pocket watch.
f) Access to a upper pocket which held a traveling inkwell and dip pen/combination pen and notebook/dispatch book.
g) Access to smoking pipes, cigars, rolling paper and tobacco pouch and a match 'safety' (a tin for holding wooden matches/safety matches)
h) Hankie.
Please look at General Thomas' mid torso by his left elbow. There seems to be a book, or hard rectangle in that area where the arm is bent. It could be a very deep pocket for such a dispatch book/orders book. Combination pens (mechanical pencil/dip pen in one case) collapsed approximately 3 to 4 inches in length. Easy to fit into a vest pocket/watch pocket.
