By early June, the entire western side of the Kamyschly Ravine was densely entrenched, and Zuckertort’s artillery preparation (
Across from Hill 124, Generalmajor Ludwig Wolff’s 22. Infanterie-Division had assembled two battalions from Oberstleutnant Rudolf Buhse’s IR 47 and two battalions from Oberst Dietrich von Choltitz’s IR 16 on Hill 191.8 on the eastern side of the Kamyschly Ravine, overlooking the Soviet positions. This was a very dangerous space, as both sides regularly traded sniper and mortar fire across the 400-yard-wide ravine, so neither could move troops around much in the daylight. Nevertheless, the Germans managed to manhandle three batteries of 28/32cm Nebelwerfer 41 multiple rocket launchers from III./schweres Werfer-Regiment 1 up onto their hill during Zuckertort’s five-day artillery preparation – apparently without being noticed.28
Petrov expected that an attack against Sectors III and IV was imminent, and on the night of June 6/7 he ordered all frontline units to conduct counterfire against suspected German assembly areas at 0255hrs on June 7.

Laskin’s division was supported by Colonel Josef F. Shmelkov’s 134th Howitzer Regiment, equipped with a rather obsolescent collection of ten 152mm M1909/30 howitzers and about 20 122mm M1910 howitzers. Shmelkov’s artillery fired against positions held by the 22. Infanterie-Division for 20 minutes, but achieved little since they had to conserve their ammunition.29At 0315hrs on June 7, Zuckertort’s artillery opened fire again, but this day was different. This day was “X-Day” – the beginning of the German ground assault. The
