To the south, a major Red Army assault aimed at the juncture of the 1st and 4th Panzer Armies had been successfully repulsed on 14 July by the division-sized Korpsabteilung C. The 1st Ukrainian Front shifted their attack further south, and after an immense artillery and air bombardment assaulted the already weakened 349th and 357th Infantry Divisions. The 349th Infantry Division collapsed under the assault, the survivors falling back in disarray. Due to the actions of Korpsabteilung C and 357th Infantry Division, the 1st Ukrainian Front breakthrough was only 3-4 kilometers wide. Despite this, the 1st Ukrainian Front continued to advance towards the towns of Zolochiv and Sasiv, driving a wedge between XIII Army Corps and the neighboring XLVIII Panzer Corps.
