The German Army's Massive Logistical Support for Its Verdun Operations

Concrete 380mm Artillery Position Built at Duzey 17 Miles from Verdun

During the long and careful buildup for their Verdun offensive, Operation Gericht (Judgment), the Germans had 14 railways at their disposal and managed to concentrate seven army corps and extraordinarily powerful artillery, comprising at least 3,000 guns of all calibers with  654 heavy artillery pieces over 100mm, including 30 over 210mm, for attacking the French. Mounting the intentionally attritional offensive required the supply of  stupendous amounts of artillery ammunition over a prolonged period. This presented unique challenges for Germany's planners. Their response was remarkable.

Army logistics at the Battle of Verdun would rely heavily on a multi-faceted rear area construction program and the use of main line railroads and a moveable system of narrow-gauge rail lines inside the initial operational sector—the fortress sector on the eastern heights of the Meuse.  The distinction between the operational and rear areas is a little murky for the 1916 Battle of Verdun. Much of the artillery of the German Army, including most of its heavy's remained some distance from the infantry operations and the logistical operations extended all the way back to Germany.  For purposes of this article only, the map below shows the distinctions we are making.

A secondary issue for the offensive was the long-term care of its troops which were to be assigned full-time to the sector rather than rotated regular as their opposing forces in the French Army would be.  Roughly 30 to 40 percent of the total manpower allocated to the Fifth Army at Verdun was strictly dedicated to rear-area support rather than frontline combat. So, for the duration of the battle, logistical operations were intermingled in the fighting area as major artillery units were firing away from the rear, i.e. the area north and east of the French fortress zone.

This  German rear area at Verdun during the fighting would serve as the logistical and structural lifeline for the Fifth Army. Known as  Etappengebiet (staging/rear areas), these zones were designed to withstand heavy French artillery, keep troops physically fit for the brutal "meat grinder" of Verdun, and manage a massive influx of casualties.  It was highly organized, featuring elaborate trench networks, concrete emplacements, and an excellent localized railway network and light trench railways that moved troops and supplies to the battlefront. Moving millions of heavy artillery shells required massive labor forces. This included thousands of wagon drivers, horse handlers, and specialized mechanical transport units operating trucks to move supplies from depots to the front.  This infrastructure allowed the Germans to conduct 300 days of intense artillery fire. 

Surviving Structures at Camp Marguerre

German engineers created a number of permanent (concrete rather than canvas) structures to support operations at Verdun.  The most famous surviving example is Camp Marguerre (located in the Spincourt Forest, about 12 miles behind the front lines). Built under the direction of Captain Hans Marguerre, it was classified a Special Concrete Factory Department and also served as a premier rest, refit, and training camp.  Another priority was for amenities and hygiene for the troops. The men  rotated out of the trenches, to camps that offered running water, bathhouses (Badeanstalten), barbers, and regular athletic events. Regimental bands played, and the command even sanctioned official brothels nearby to keep the troops jolly.

The scale of medical support was similarly extensive. Advanced Dressing Stations (Verbandplätze) were located roughly 800 yards to a mile behind the trenches and were heavily reinforced concrete bunkers. They were designed with blast-shielded windows facing away from the enemy line to let in natural light so doctors could triage and perform emergency amputations safely under fire.  Field Hospitals (Feldlazarette) were positioned roughly 10 to 15 kilometers (6–9 miles) behind the front. These stationary facilities typically cared for 200–300 patients at a time. Many were constructed directly into the hillsides or utilized reinforced local schoolhouses and churches in occupied towns.

A notable feature of the battle was the extensive light, narrow-gauge rail network developed by the German Army at Verdun.  Known as the Heeresfeldbahn (Army Field Railway), it featured assembled portable steel rails mounted to gauge on steel ties. These track sections could be handled by a few men, laid directly onto flattened dirt or mud without extensive ballasting, and quickly bolted together like a giant model train set. If a section was destroyed by French shellfire, it could be unbolted and replaced by German railway troops in a matter of minutes. The workhorse of the Verdun network was the Brigadelokomotiven (DFB), a heavy-duty, 0-8-0 steam engine designed specifically for the field army. It was built to burn low-quality coal or wood and could reach speeds of up to 25 km/h (15 mph) while pulling dozens of wagons. For the transporting the wounded, specially modified, four-wheeled narrow-gauge wagons were fitted with layered stretcher racks and protective canvas covers . Incidentally, these smaller railroads play a prominent role in Arnold Zweig's classic novel, Education Before Verdun.

The major shortcoming of the German logistical  network at Verdun  was the lack of reliable, well-maintained rear-area roads. These were devastated by French artillery firing from the west side of the Meuse, eventually causing the German high command to expand the battle across the river.  They never developed a reliable motorized transport system to match the French Army's Voie Sacrée.
