A new history of the most crucial few months of the Arctic Convoys, when Germany's air power forced the Allies to retreat to the cover of winter.
    
   Between spring and autumn 1942, Germany was winning the battle of the   Arctic Convoys. Half of PQ-15 was sunk in May, PQ-17 was virtually   obliterated in July, and in September 30 percent of PQ-18 was sunk. The   Allies were forced to suspend the convoys until December, when the long   Arctic nights would shield them.
Mark Lardas argues that in 1942, it was Luftwaffe air power that made   the difference. With convoys sailing in endless daylight, German strike   aircraft now equipped and trained for torpedo attacks, and bases in northern   Norway available, the Luftwaffe could wreak havoc. Three-quarters of the   losses of PQ-18 were due to air attacks. But in November, the Luftwaffe was   redeployed south to challenge the Allied landings in North Africa, and the   advantage was lost. Despite that, the Allies never again sailed an Arctic   convoy in the summer months.
Fully illustrated with archive   photos, striking new artwork, maps and diagrams, this is the remarkable   history of the Luftwaffe's last strategic victory of World War II.
