Stopped at Stalingrad deals with the Luftwaffe's actions in and around the Crimean peninsula from 1942 to 1943. Probably the most interesting part of the book deals with Fliegerfuhrer Sud and it's mission to clear the Black Sea of the Soviet naval presence. Stopped at Stalingrad also deals with the use of air power in the taking of Sevastapol, the actions against the Soviet forces landed on the Kerch peninsula, and the overall use of German airpower in supporting the march on the Don.
Hayward also discusses why Hitler felt the Luftwaffe could airlift enough supplies to sustain 6th Army after it was cut off around Stalingrad by Soviet troops.
This book is a good case study of how the Luftwaffe operated in tandem with the army and naval forces, and Hayward points to the Luftwaffe as one of the major contributors to Germany's initial successes against the Soviets.
I thuroughly enjoyed this book, and I would recommend it to anyone interested in learning more about the tactical air-support role the Luftwaffe played (specifically in the Southern Front of the Eastern Theater of Operations).
