I'm researching the Battle of Lake Narocz on the Eastern Front in 1916 which was then in Russian controlled Poland. It is now called Lake Naroch and is modern day Belarus.

I'd be grateful for any information and any especially pictures. I include a small summary of the battle :

At the height of the war One with French forces under heavy attack at the fortress town of Verdun, the French Commander in Chief Joseph Joffre appealed to his allies in early 1916 to launch offensive operations of their own in order to divert German resources and ease pressure on Verdun. Russia responded quickly and identified an area of perceived weakness in the German line just to the east of Vilnius. The plan was to assault it with a much larger force in the hope that they could break through and cause the Germans to relocate troops and resources from Verdun. Tsar Nicholas II and the Russian chief of staff, General Mikhail Alekseyev planned an offensive at Lake Naroch itself, where 1.5 million Russian soldiers would face just 1 million combined German and Austro-Hungarian troops, under the command of General Eichhor's German Tenth Army.

The Russian offensive, led by General Smirnov's Second Army (part of General Alexei Evert's estern Army Group) launched on the 18th March 1916, began with a two-day-long artillery bombardment (the longest yet seen on the Eastern Front) against the Germans that for the most part failed to do the planned damage due to inaccuracy. Russian infantry troops from the Tenth Army, commanded by General Alexei Evert, then moved forward across no-mans land in groups rather than spreading out against a heavily fortified German defence, suffering heavy casualties. Due to the spring thaw,
the ice on the lake was thin and it is believed thousands of men perished falling through the ice, in addition many of the approaching infantrymen also became bogged down in the thick mud, slowing the offensive. The lack of an effective supply system also hampered the Russians, as the battle
stretched on for almost a month. The floundering attack gained several kilometres of land in some places but made little impact on the German defences, or to their troop allocations.
