The Military History of WWII by Trevor Nevitt Dupuy Col. U.S. Army in 14 volumes For Sale

Originally published in 1962 this is a 5th edition which may account for the discrepancy in the number of volumes between sets. Some were 18 volumes this set is 14 volumes. It appears complete, beginning with events of 1939 and ending with the atomic bombing of Hiroshima and Nagasaki. Tons of black and white photographs along with maps of important campaigns. The author was a retired Colonel in the U.S. army and a respected military historian. Just perusing a few volumes I found them captivating.
These books measure 7-1/2 x 8-5/8 and average about 100 pages each.
