Petrov divided the SOR into four defensive sectors, starting clockwise with Sector IV holding the Bel’bek River valley, Sector III holding the Mekenzievy Mountain area, Sector II holding the Chernaya River valley and Fedyukhiny Heights, and Sector I holding the coastal strip around Balaklava. He anticipated that the Germans were most likely to make their main effort against Sectors III and IV, so he placed his best units and commanders there. General-Major Vasily F. Vorob’ev, commander of the 95th Rifle Division, was assigned Sector IV; in addition to his own division, Vilshansky’s 8 NIB, 13 ad hoc battalions and two artillery regiments were put under his command. General-Major Kolomiets, commander of the 25th Rifle Division, took over Sector III, which also included Zhidilov’s 7 NIB, the 3rd Naval Infantry Regiment, the 1st Perekop Naval Infantry Regiment, and ten other ad hoc battalions. Altogether, Vorob’ev had more than one third of the available forces in his sector and Kolomiets had one quarter in his, which left only weak covering forces in the other two sectors. Zhukov had done a remarkable job forming 30 ad hoc battalions from available resources, including six naval infantry battalions, an NKVD battalion, and a plethora of units composed of VVS ground crews and personnel from the naval schools in Sevastopol. Yet aside from Petrov’s 25th and 95th Rifle Divisions and the two naval infantry brigades, none of these were really cohesive units with strong leadership. The question was whether they could they hold out against Manstein’s overextended but better led and equipped AOK 11.
Petrov did have a few aces up his sleeve. Although some air units had retreated to the Caucasus, Ostryakov had re-energized the remaining VVS-ChF units at Sevastopol into an effective force that hindered Fliegerkorps IV from making full use of the captured Sarabus airfield, north of Simferopol. The Germans were only able to move two
Another factor in Petrov’s favor was naval gunfire support. Although the Black Sea Fleet’s heaviest units had retreated to ports in the Caucasus, the fleet formed a Naval Gunfire Support Group comprising the elderly light cruisers
Petrov realized that his main task was to parry Manstein’s initial offensive long enough for the Stavka to send him reinforcements from the North Caucasus Military District. Winter was approaching fast, and although not as harsh in the Crimea as in central Russia, the weather would hinder the attacker far more than the defender. Despite having a motley assortment of 27,000 ground troops to defend a 29-mile-long perimeter, Petrov was determined to exact a high price from Manstein’s assault forces.
