Between 5:30 and 6pm late in the afternoon of 4th August 1773, the action heated up across the battlefield. Yet a third attempt by Stollenian engineers to blow the single small bridge across the River Elbow failed. General von Tschtschke's artillery, nevertheless, managed to inflict heavy casualties on parts of the Zichenauer line which gave way. So too did the Grand Duchy's corps of Jaeger zu Fuss during a stiff exchange of skirmish fire atop a wooded hill at the eastern end of the field.
While Zichenauer forces continued to move into position where they were able, strangely very little musket or artillery fire came from General de Latte's units. As the Grand Duke Irwin-Amadeus II held forth in the background, to anyone who seemed remotely interested on the benefits of genuine Harris Tweed clothing in a Northern European climate, General von Tschatschke was able to note in his pocket journal, "What the devil is that bounder de Latte doing over there? Things just keep getting curiouser and curiouser!"
By the time his pocketwatch chimed six 0'clock, the situation looked bleak for General de Latte along his western flank. His independent company of the Wolmar-Bock Regiment had been reduced to below 50% of its original strength due to continued fire from the single Stollenian gun in the Lesser Redoubt. It fled the battlefield unceremoniously, becoming tangled in the process with a company of O'Malley's Irish Grenzers immediately to its rear, which had functioned as its third and fourth lines, the two units operating together as a single entity.
