When I look at all the Osprey booklets that the author has written about German fighter units in the Great War I wonder how long it will be before one sees a one-volume work from Osprey on the topic. Be that as it may, what's interesting about this unit is that it was on the cutting edge of the German offensives in the West in 1918, often in contact with American combat aviation. Also, while I had wondered why it was not mentioned in a parallel Osprey publication about how Rudolf Berthold had gone on to be a "free corps" commander post-1918, in this booklet you get those details, and the story is even sadder than I had thought. Worth having if you can come up with a copy for a reasonable price. ( )
