JG26 spent almost all of its time fighting the air war of WWII against the western Allies. Small parts of it fought in the Med and on the Eastern front for a very short time. What this means is that they were at the tip of the spear at the start of the war and were an essential part of the shield during the latter half of the war.
The author does a great job covering all the experiences of its pilots, the aircraft used, and the evolving tactics of a war that developed not only in material, but also on the technical and human fronts. When the unit transfers to a new type of fighter he explains what this meant for the men involved. He does describe the pilots, not only the aces but also the green pilots assigned to JG 26, in detail. He does this by using their written experiences, official records and testimonies by fellow pilots. This way the unit comes alive, showing the reader what it was like.
The historical detail is staggering, but never overwhelming. The book flows very well and this keeps the reader connected to the overall story. As the war progresses you read how the pilots struggled, knowing that each mission could be their last. The air superiority by the Allies was overwhelming, only experience, and at times raw luck, kept some of them alive.
The book follows the unit from its creation till war's end, making this a must read if you want to learn more about the Luftwaffe during WWII.
