Esposito. The U.S.-Mexican War is not well covered in military history, but it was a pivotal action in the histories of both the U.S. and Mexico. For the U.S., with a small professional army, it was the breeding ground for officers and strategies that marched to war in 1861. The Mexican Army was a large professional force, tempered by civil war and local uprisings. This is still a colorful era for martial uniforms as shown in this excellent illustrated volume. 123 pages, 8"x 10", softcover.
