2nd Shock Army was to break through the defense line of the III SS Panzer Corps at the Orphanage Hill, force their way to the town of Jõhvi in the west and reach the Kunda River by 1 August. To accomplish this, Govorov was ordered to destroy communications behind the German forces and conduct air assaults on the railway stations of Jõhvi and Tapa on 26 July. Comparison of forces Soviet There is no complete overview of the order of the Soviet forces or the detachment sizes in the Battle of Tannenberg Line. For the attack on 29 July, Govorov concentrated all of the capable Soviet units, consisting of 11 divisions and six tank regiments. The Soviet units that had suffered losses were brought up to strength with fresh manpower. The delivery of Soviet heavy artillery complimented the nine divisions of the 109th, the 117th and the 122nd Rifle Corps. The 109th and 117th Corps were concentrated close to the Sinimäed, while the 122nd Rifle Corps was sent to the southern section, near the church of Vaivara Parish. The positions of the 11th Infantry Division were mainly attacked by the 35,000-strong 8th Army with their 112th Rifle Corps, two fresh tank regiments and 1,680 assault guns, deployed in nine artillery regiments and 150 armored vehicles. The armored forces included the brand-new IS-2 tanks with extra armor and a 122mm gun. The weakness of the tank was its limited ammunition capacity (only 28 rounds) and long reloading time for its main gun. The forces were supported by the 576-strong 13th Air Army.
