Battle of Combles

The battle of Combles was one of the last major actions of the Somme in 1916. From 25 to 28 September, French and British forces launched a coordinated attack to encircle and take the fortified town of Combles, a key point in the German defence southeast of the front. After massive artillery preparation, French troops advanced from the east and south, British and dominion forces from the west and north. Street fighting, massive use of grenades, and artillery support allowed rapid progress: overwhelmed, the Germans abandoned the town, which was taken on 26 September. Victory at Combles opened the road to Bapaume and weakened the entire German dispositions in the region.

Since July 1916, Combles, fortified by a network of trenches, underground shelters, and blockhouses, had been a strategic lock south of the Somme. Allied headquarters sought to end German resistance and exploit recent successes at Guillemont and Ginchy. Franco-British coordination was exemplary: converging attacks, cross barrage fire, air support. Allied troops, exhausted but determined, advanced in rain and mud across devastated ground. Combles, reduced to ruins, was defended to the last, but German reserves were too weak to contain the pressure. Encirclement from the east (French) and north (British) cut off the defenders' retreat, and they were captured in large numbers.

The offensive began on 25 September with intense artillery bombardment, followed by rapid advance of Franco-British infantry. The French attacked via Fregicourt and Rancourt, the British via Lesbœufs and Morval. Street and trench fighting was violent: massive use of grenades, flamethrowers, assaults on blockhouses and cellars. Shock units penetrated the town from several directions, disrupting enemy defence. Allied aviation (reconnaissance, fighter, bombing) helped pin German reinforcements in the rear. Germans attempted a few counter-attacks but, encircled, surrendered en masse. Clearing the town, strewn with corpses, traps, and rubble, took several days.

The capture of Combles was a major tactical victory for the Allies, who seized one of the last German bastions south of the Somme. Essential Franco-British cooperation was praised by staffs. More than 2,000 German prisoners were taken, along with many guns and equipment. The German front, weakened, had to fall back to new positions, preparing the Hindenburg Line of 1917. Casualties, though heavy, illustrated the harshness of trench warfare: destroyed houses, booby-trapped streets, corpses and wounded everywhere. Combles, totally razed, became a high place of Franco-British memory. The battle inspired new tactics for coming offensives, notably combined-arms coordination, encirclement, and rapid exploitation of breakthroughs.
