This modern stronghold, which the Crown Prince called “the N.E. angular pillar of the permanent fortifications of Verdun,” occupies at Hill 388 the culminating point of the hard limestone plateau which forms the region of Verdun. Lying between Bras Ravine (which descends towards the W. and the Meuse) and Vaux or Bazil Ravine (extending towards the E. and the Woevre), the fort dominates the entire region. As the key of the battlefield it was fiercely disputed. [Illustration: DOUAUMONT FORT IN JANUARY, 1916.] Before the battle of 1916 it was only bombarded twice by the German artillery. Of the 250 shells fired at it early in November, 1914, 170 reached the mark without, however, causing serious damage. The few 8-inch shells received on March 29th, 1915, did no damage whatever. [Illustration: THE FRONT ON THE MORNING OF FEBRUARY 26TH (26/2), AFTER THE GERMANS HAD OCCUPIED THE FORT BY SURPRISE, AND ON THE MORNING OF THE 27TH (27/2), AFTER THE FRENCH COUNTER-ATTACK.] On February 25th, 1916, almost at the beginning of the battle, units of the German XXIVth Infantry Regiment (IIIrd Brandenburgers), wearing French Zouave uniforms, surprised and occupied the fort. On the morning of the 26th the French 153rd D.I. (20th C.) counter-attacked fiercely five times, advancing their line beyond the fort and surrounding the enemy on three sides. Thanks, however, to a communicating trench connecting up with their lines, the enemy were able to keep their ground. From the 26th to the 29th they furiously attacked the approaches of the fort without being able to surround it. A redoubt, 200 yards E. of the fort, was alternately lost and recaptured three times on the 26th. From March 8th to May 19th the fighting continued with varying fortune. [Illustration: THE ENTRANCE TO DOUAUMONT FORT IN JANUARY, 1916.] From the 19th to the 22nd French heavy guns bombarded the fort, the explosion of a shell on the 20th causing hundreds of victims. To hamper the enemy Intelligence Service six of their observation balloons were destroyed by a French flying squadron on the morning of the 22nd. At 11.50 the 10th Brigade (5th D.I.) attacked the fort and its approaches. At noon the 129th line regiment occupied the N. and N.W. corners of the fort. The 74th regiment was unable to take the N.E. corner, but the 36th succeeded in capturing all the trenches west of the Fort. During the night and all the next day the enemy intensified their bombardment and increased the number of their counter-attacks, without breaking through the defences of the 10th Brigade, which maintained all its gains until relieved on the night of the 23rd. Exasperated at this check, the Germans, on the 24th, engaged no less than an army corps of reinforcements and retook the fort.
