 While the operation on the northern side of the salient began with a 45-kilometre-wide (28 mi) attack front, by 6 July it had been reduced to 40-kilometre-wide (25 mi). The following day the attack frontage dropped to 15-kilometre-wide (9.3 mi), and on both the 8 and 9 July penetrations of only 2-kilometre-wide (1.2 mi) occurred. By 10 July, the Soviets had completely halted the German advance.
