The Battle of Megiddo, fought September 19-21, 1918, stands as a masterpiece of operational art and the last major cavalry charge of a modern army. British General Edmund Allenby, commanding British and Commonwealth forces in Palestine, launched an offensive designed to destroy the Ottoman Fourth Army and open the path to Damascus and Constantinople. The battle involved approximately 84,000 British and Commonwealth troops supported by 540 guns against approximately 100,000 Ottoman and German troops. The result was a complete Ottoman defeat, the capture of over 75,000 prisoners, and the effective destruction of Ottoman military power.

Allenby's Campaign and Strategic Positioning

By September 1918, General Edmund Allenby had been campaigning in Palestine for nearly two years, advancing from Egypt northward toward the Ottoman heartland. The campaign had involved victories at Gaza and Jerusalem, but Ottoman forces had stabilized their lines in September 1918, holding positions in the hills around Megiddo. Allenby's plan was audacious: instead of a frontal assault against Ottoman fortified positions, he planned a cavalry exploitation once the Ottoman line was broken. The success of this operation depended on achieving surprise, achieving a decisive breakthrough, and then exploiting that breakthrough with mobile forces before Ottoman reserves could arrive.

Allenby achieved surprise through meticulous deception. He convinced Ottoman commanders that the main attack would come in the south, away from the Megiddo position. British forces concentrated in the north for the attack on Megiddo. On September 19, British infantry attacked Ottoman positions frontally, while cavalry forces maneuvered toward the Ottoman rear. The Ottoman Fourth Army, outnumbered and out-maneuvered, began to disintegrate. As Ottoman forces attempted to retreat, they discovered that British cavalry had cut the main roads of retreat.

Breakthrough and the Cavalry Exploitation

On September 20, as Ottoman forces attempted to retreat northward, approximately 5,000 British cavalry, commanded by Major-General Henry Chauvel, swept across the Megiddo Plain toward the town of Nazareth. The cavalry advance was a textbook example of exploitation. Moving rapidly, the cavalry cut telegraph and telephone lines, captured Ottoman supply depots, and occupied key road junctions. Ottoman forces attempting to retreat found themselves cut off. Thousands of Ottoman soldiers, lacking leadership and organization, simply surrendered. The speed of the cavalry advance prevented the Ottoman Fourth Army from establishing a new defensive line or conducting an orderly retreat.

By September 21, the Ottoman Fourth Army had ceased to exist as a coherent military force. Over 75,000 Ottoman and German soldiers were captured. Turkish losses in killed and wounded were estimated at 20,000-30,000. Allenby continued his advance, occupying Damascus and driving toward Aleppo and Constantinople. The Ottoman Empire, already weakened by years of war, could not recover from the loss of the Fourth Army. The Ottoman government sought armistice terms, and on October 30, 1918, an armistice was signed that effectively ended Ottoman participation in World War I. Megiddo demonstrated that cavalry could still play a decisive role in modern warfare when committed at the right moment and place, and that operational excellence could produce overwhelming victory even against numerically similar forces.
