Tolbukhin knew that airpower would be the crucial element of this operation, and he wanted to take the Luftwaffe out of the battle as quickly as possible. Hoping for a knockout blow, Tolbukhin decided to begin his Crimean offensive with a massive air attack by 8th Air Army on April 7 against the Luftwaffe bases and German artillery positions on the Perekop. Having learned the value of a specialist close-air-support unit from Fliegerkorps VIII, the 8th Air Army was provided with General-Major Vasiliy Filin’s 7th Ground Attack Aviation Korps (7 ShAK), which possessed 108 Il-2 Sturmoviks. Barkhorn was away on leave at the start of the Soviet offensive and II./JG 52 was apparently caught off guard by the scale of the Soviet onslaught; it got only a few fighters in the air in time. Protected by dozens of Yak-7 fighters, groups of Soviet Sturmoviks came in low over the treeless Perekop Isthmus, shooting up artillery positions and anything else that was visible. Although the Germans claimed that flak inflicted heavy losses on the raiders, the VVS raids were not seriously disrupted.2
The next morning, April 8, 1944, the artillery of both the 2nd Guards Army and the 51st Army opened fire at 0800hrs. The Soviet artillery delivered a punishing 2½-hour-long prep fire against the Axis positions, from tube and rocket artillery, as well as heavy mortars. The 8th Army also returned again in strength, strafing and bombing the German positions. This time, II./JG 52 was able to intercept some of the Soviet bombers, although it made little difference. Soviet aircraft were everywhere over the Crimea. At 1030hrs, both Soviet armies commenced their ground attacks.
The 51st Army put its main effort against the center of the Axis perimeter around their Sivash lodgment, with the 91st Rifle Division and 32nd Guards Tank Brigade (32 GTB) attacking the Romanian 10th Infantry Division. The Romanian positions were well protected by mines and artillery, which broke up the Soviet attack. German StuG IIIs supporting the Romanian defense knocked out 27 of the 32nd Guards Tank Brigade’s 53 tanks. Surprisingly, a supporting attack made by Koshevoi’s 63rd Rifle Corps’ 267th Rifle Division and the 22nd Guards Tank Regiment against the Romanian 19th Infantry Division on the eastern end of the lodgment was more successful. Upon Tolbukhin’s specific recommendation, Koshevoi sent the 2nd Battalion/848th Rifle Battalion to wade across the shallow Lake Aygulskoe to outflank the Romanian positions. Although German sources claim that the Romanian 94th Infantry Regiment panicked and ran, Koshevoi notes that the enemy fell back slowly to a second line of defense and that only 550 prisoners were taken.3
When Kreizer realized that he was achieving no success in the center but that the Romanian 19th Division was buckling, he shifted the depleted 32 GTB and more infantry to reinforce this sector.
