French artillery bombarded the German lines overnight and then abated until 6:00 a.m. when a bombardment, slowly increasing in intensity began on the fronts of VII, XIV and I Bavarian Reserve corps, which from mid-morning reached the extent of Trommelfeuer.
Lulls in the fire were ruses to prompt German infantry to emerge from shelter, only to be caught in more Trommelfeuer; the German artillery reply was sparse. The French infantry assembled unseen and the advance began after several mines were sprung, obtaining a measure of surprise. The main French attack was received at 11:00 a.m. on the left of XIV Corps and against I Bavarian Reserve Corps, from Lens to Arras, as a second attack began against the centre of XIV Corps along the Béthune–Lens road, which was repulsed by a counter-attack. The 28th Division on the Lorette Spur, was forced out of the front trenches, with many losses and in the evening a battalion of Jäger was sent forward. Further south, the villages of Ablain-St. Nazaire (Ablain) and Carency were held against determined French attacks. By noon 2.5 mi (4 km) of the German front defences had fallen and the French had penetrated up to a depth of 1.9 mi (3 km).
In the I Bavarian Reserve Corps area (General Karl von Fasbender), the 5th Bavarian Reserve Division (General Kress von Kressenstein) south of Carency, was pushed back to a line from Cabaret Rouge to Neuville-St. Vaast (Neuville) and French troops advanced as far as artillery positions around Givenchy-en-Gohelle (Givenchy), where reinforcements arrived at noon and managed to forestall a new French attack. To the south, the 1st Bavarian Reserve Division (Lieutenant-General Göringer) managed to repulse the French in hand-to-hand fighting and then enfilade the French further north, who had broken through at La Targette. Crown Prince Rupprecht applied to Falkenhayn, for the two divisions in OHL reserve and the 115th Division (Major-General von Kleist) was moved behind the 5th Bavarian Reserve Division. The 58th Division (Lieutenant-General von Gersdorf) went into the 6th Army reserve and closed up to Lens, as artillery also released from the OHL reserve came forward. On the southern flank of the breakthrough, French attacks were also pushing slowly through the network of trenches known as the Labyrnthe. North of Ecurie, Bavarian Reserve Infantry Regiment 12 took over more ground to the north and prevented the French from widening the breakthrough and in Neuville St. Vaast a counter-attack by a battalion of Bavarian Reserve Infantry Regiment 10 retook the east end of the village and many of the field guns which had been lost earlier. A defence line was improvised between Neuville and La Folie to the north and was used to engage the French troops further north with flanking fire. Bavarian Infantry Regiment 7 was rushed up from reserve to counter-attack the French on Vimy Ridge.
