Lake Naroch Offensive

The Lake Naroch Offensive in 1916 was an unsuccessful Russian offensive on the Eastern Front in World War I. It was launched at the request of Marshal Joseph Joffre and intended to relieve the German pressure on French forces. Due to lack of reconnaissance, Russian artillery support failed to overcome and neutralise the well-fortified German defenses and artillery positions, leading to costly and unproductive direct attacks, hindered by the weather. On 30 March General Evert ordered to stop the offensive.
Under the terms of the Chantilly Agreement of December 1915 Russia, France, Great Britain and Italy were committed to simultaneous attacks against the Central Powers in the summer of 1916. Russia felt the need to lend troops to fight in France and Salonika , and to attack on the Eastern Front, in the hope of obtaining munitions from Britain and France.
