Text from Osprey's "Slovakian And Bulgarian Aces of WW2"
After a while here's an update to the history of 13.(Slow)/JG 52 with biography of Izidor Kovárik, second ranking ace of Letka 13, who fought gallantly on the eastern front and destroyed 28 Soviet aricraft, only to die in his native country while flying a Go 145 biplane trainer...
Born on 29 March 1917 in Kopčany, Izidor Kovárik was the son of a carpenter. Joining the air force in the late 1930s, he and his great friend Režňák graduated from pilot training together. Assigned to 11th Squadron (Letka 11) in December 1939, Kovárik fought on the eastern front between June and September 1941, when his squadron supported operations against partisans in the Zhitomir and Ovruc areas. He flew eight combat sorties in B.534s during this time, strafing and bombing enemy forces.
Kovárik's second tour in the East began in October 1942 with first front team of Letka 13, but flying Praga E.241 liaison aircraft rather than fighters. He eventually started flying Bf 109Es and soon claimed 28 confirmed kills in combat over Caucasus and Kuban - 9 LaGG-3s, 6 Yak-1s, 6 I-16s, two I-153s, two Il-2s and single MiG-3, DB-3 and Boston. His most successful day came on 29 May 1943 when he shot down four Yak-1s. Kovárik was shot down just once, on 14 March 1943, while returning with Režňák from a ground attack mission during which he had expended all his ammunition. Režňák attacked a formation of DB-3 bombers and shot down one. Kovárik also attacked the Soviet formation to draw some of the defensive fire away from Režňák, despite his magazines being empty. His Bf 109G-2 (WkNr 10473) was hit and he had to force land in a swamp near Akhtanizovskaya. The aircraft was destroyed but he escaped uninjured.
Kovárik recieved many decorations, inculding Slovakian Silver Medal of Military Victory Cross, the Silver Military merit Cross, The Gold, Silver and Bronze Medals for Heroism, the German Iron Cross 1st and 2nd class, Ehrenpokal and the Deutsches Kreuz in Gold. Like Režňák, he too was promoted to the rank of Zastavnik.
Upon returning to Slovakia, Kovárik served with the Readiness squadron (Pohotovostna letka) until April 1944, when he was transfered as an instructor to the Slovak Air Arms' flying school at Tri Duby. He died on 11 July 1944 shortly before the uprising when, during a training flight, the wing of his Gotha Go 145 biplane broke off for unexplained reasons and the aircraft crashed near Tri Duby. Both Kovárik and his student were killed.
