Initially flying Italian-supplied Fiat G.50s, the Croat forces suffered heavy losses during 1942 whilst flying alongside JG 52 in the southern sector of the Russian front. Despite this, a significant number of kills fell to future aces such as Cvitan Galic and Mato Dubovak during this time, and when the units re-equipped with Bf 109G-10s in 1943, battle-seasoned Croat pilots started to rack up impressive scores. This book reveals how, by 1944, Croat air groups were defending Yugoslavia from British and American air raids, and in the final months of the war a handful of surviving pilots fought on until final defeat in May 1945.
