For an ongoing project I am trying to put together a collection of images of battles within the boundaries of Texas. I am familiar with most of the Harpers Weekly and Frank Leslie engravings and woodcuts, etc. What I am really looking for is any hand-drawn sketches of Texas forts and/or battles (Sabine Pass, Galveston, Port Lavaca, Matagorda, Fort Esperanza, Palmito Ranch, etc.). If you know of any such drawings in public or private collections I would appreciate it if you would let me know.Thanks.
