During a punishing snowstorm, the German army launches a new attack against French forces on the high ground of Mort-Homme, on the left bank of the Meuse River, near the fortress city of Verdun, France, on this day in 1916. The Battle of Verdun began February 21, 1916, with a German bombardment on the symbolic city of Verdun, the last French stronghold to fall during the Franco-Prussian War of 1870-71. Though the Germans had advanced speedily since the start of their advance, capturing Verdun's major protective fort, Fort Douaumont, on February 25, the French were by no means ready to give way, and the battle soon settled into a stalemate, with heavy casualties on both sides. On the night of Douaumont's capture, General Philippe Petain took over the French command of the Verdun sector, vowing to hold the fort at all costs and inflict the maximum number of German casualties in the process. The German objective was similar: in the words of General Erich von Falkenhayn, chief of the general staff, they aimed to bleed the French white.
Knowing the Allies planned to launch a major offensive at the Somme River that July, the German high command was determined to keep French troops and resources devoted to the defense of Verdun throughout the spring. To do this, Falkenhayn determined that he needed to change the focus of the German attacks, shifting them from Verdun and the inner ring of forts that protected it—the core of Petain's defensive strategy—to the flanks of the French lines surrounding the city.
To that end, on March 6, after receiving fresh artillery supplies, the Germans attacked along the west bank of the Meuse, beginning the so-called Battle of the Flanks with a preliminary artillery bombardment every bit as intense as the one of February 21. Although under heavy fire from French artillery positions, the Germans managed to cross the river at Brabant and Champneuville to step up their assault on Mort-Homme, which held, though 1,200 French soldiers were captured over the course of two days' fighting. The Germans made good progress in the area in general, however, capturing nearby positions before the French began their aggressive counterattacks. The struggle for Mort-Homme itself went on for more than a month, with thousands dying on both sides of the line, but the Germans never captured the position.
Fighting at Verdun would continue for 10 months, making it the longest battle of World War I. Paul von Hindenburg—who replaced Falkenhayn that summer—finally called a halt to the German attacks on December 18, after more than a million total casualties had been suffered by German and French troops.
