Meanwhile, Generaloberst Eugen Ritter von Schobert’s 11. Armee (AOK 11) pursued the battered Soviet 9th Army to the Dnepr, but the Soviets managed to slip across the river, blow up the main bridges, and establish a hasty defense. Recognizing that German forces could cross the Dnepr at any time, Stavka Directive No. 00931, issued on August 14, activated the 51st Army in the Crimea and it was tasked to “hold the Crimean Peninsula in our hands to the last soldier.” Although Batov’s 9th Rifle Corps formed the core of the 51st Army, General-Colonel Fyodor I. Kuznetsov was brought down from Leningrad to take command of the new formation. In addition to Batov’s two regular rifle divisions, Kuznetsov was provided with two newly formed reserve rifle divisions from the Orel Military District, four militia divisions, and the 5th Tank Regiment. All told, Kuznetsov’s 51st Army had about 95,000 troops, but relatively little artillery or transport. Stavka Directive No. 00931 also made the Black Sea Fleet subordinate to Kuznetsov.
Kuznetsov was forced to begin throwing together a defense at the Perekop Isthmus in mid-August with most of his units still en route or severely understrength. Roughly 30,000 local civilians were used to assist the Red Army in fortifying the Perekop Isthmus and Chongar Peninsula, but Kuznetsov was ordered to “immediately clear” these areas of “anti-Soviet elements.” On August 16, NKVD detachments rounded up virtually all of the remaining Crimean Germans and deported them to the Urals, where most spent the next decade in labor camps operated by the NKVD. Roughly 20 percent of the Crimean Germans died in these camps.7
Kuznetsov’s deployment for battle was seriously hindered by faulty intelligence issued in General Staff Order No. 001033 on August 18, 1941:
According to information from the English military mission, the Germans are preparing sea [amphibious] operations against the Crimea in the most immediate future, while concentrating amphibious assault transports in Bulgarian And Romanian ports. The amphibious assault operation will be supported by airborne forces, which are concentrating in the Nikolayev region.8
Despite the fact that the Axis had no appreciable amphibious capability in the Black Sea in August 1941 and their airborne forces were spent after their costly victory in Crete three months earlier, the Stavka was convinced that the threat was real. Accordingly, Kuznetsov deployed 40,000 of his men along the coast to defend against a non-existent amphibious threat and 25,000 in the interior of the Crimea to defend against airborne landings. Consequently, only 30,000 troops were left to defend the vital northern approaches into the Crimea, with just 7,000 troops from Colonel Aleksandr I. Danilin’s 156th Rifle Division at Perekop. Since there were no tanks assigned to the 51st Army, the Southern Front scraped together ten T-34 tanks and 56 T-37/38 tankettes from repair depots to form the 5th Tank Regiment under Major Semyon P. Baranov; the tanks were sent by rail to provide Kuznetsov with a small mobile reserve.
On August 30, the 11. Armee conducted an assault crossing of the Dnepr at Berislav and succeeded in building a pontoon bridge across the river. The 9th Army managed to impede the German build-up across the river for a week but Schobert conducted a breakout attack on September 9–10 that shattered the Soviet perimeter and forced the 9th Army to retreat eastward in disorder toward Melitopol. The approaches to the Crimea were now open. Schobert was faced with a dilemma, since he was tasked with both seizing the Crimea and supporting Panzergruppe 1’s advance toward Rostov. As soon as he had achieved a clean breakout from the Berislav bridgehead, he directed XXX Armeekorps and XXXXIX Gebirgs-Armeekorps to pursue the 9th Army to Melitopol, while sending General der Kavallerie Erik Hansen’s LIV Armeekorps toward Perekop. German intelligence about Soviet force in the Crimea was sketchy, based entirely upon aerial reconnaissance, and they were unaware of the creation of the 51st Army. Schobert ordered Hansen to send a fast advance guard to try and seize the Perekop Isthmus by
