Kerensky, Russia’s war minister, has ordered a great offensive against the Germans and Austro-Hungarians. Brusilov, the new army commander, presided over the preparations but he has become increasingly concerned that the Russian army is in no fit state for such an undertaking. Nevertheless, Kerensky has insisted that the offensive go ahead.
After two days of artillery bombardment today the infantry attack. Their target is the Galician city of Lemberg, known to the Russians as Lvov, which was occupied in 1914 but then recaptured by the enemy the following year. Initial progress is good, particularly against the Austro-Hungarians. The assault troops find the enemy trenches largely abandoned. It appears that the Teutons have been scared away by the artillery. The Russians press on.
But the Germans have not collapsed. Fraternisation between German and Russian troops meant they were fore-warned of the offensive. They have withdrawn to positions further to the rear and left the Russian artillery to pound their empty frontline trenches. Now they are waiting for the Russian infantry.
