On September 4, 1917, during the Eastern Front of World War I, the bodies of Russian soldiers killed by chemical weapons littered the battlefield near Riga, Latvia, at the Battle of Jugla. During the fighting of the Jugla Offensive, there were no Russian survivors.
The German offensive at Jugla (Riga) erupted from September 1 to September 5, 1917. The Germans launched their attack on September 1, crossing the Daugava River south of the fortified Russian positions around Riga. One column attacked the Russian corps threatening the bridgehead, while another advanced north along the river towards Riga. Most of the fighting occurred near the Dvina bridgehead, where the Germans also attacked Russian positions along the Jugra River further northeast. Meanwhile, German forces advanced into Riga with little resistance. However, in the southern fighting and the Riga advance, most Russian troops withdrew intact. The Germans captured only 9,000 Russian soldiers, and overall casualties on both sides were minimal.
When the Germans attacked the Russian positions along the Jugra River, they employed gas shells, flamethrowers, and air strikes. Despite this, the Russians repelled the German river crossings for most of the day. Despite Russian resistance, the Germans ultimately secured bridgeheads along the Jugra River by the end of the day. The Germans employed a more fluid, infiltrating tactic rather than a straight-line assault. Advance units bypassed many defensive positions, leaving them for the main force to eliminate. While Russian cavalry, artillery, machine gun units, and some infantry fought well, the majority of infantry units fared poorly and decided to abandon their positions.
