November 17 in Military History — On This Day

The Storming of Kars

Russia's Caucasus army stormed the great mountain fortress of Kars in a daring night assault, escalading its ring of forts in the dark and taking the citadel with its garrison of some 17,000. It was one of the boldest feats of arms of the war.

The capture of Kars gave Russia control of eastern Anatolia and a prize it would keep for forty years, until the First World War — a lasting territorial gain from the war.

Battle of the Çatalca Lines

After the catastrophe at Lüleburgaz, the Ottomans constructed a desperate last line of defense at Çatalca, roughly 40 kilometers from Constantinople. The Çatalca Lines exploited a narrow peninsula between the Black Sea and the Sea of Marmara, creating a natural chokepoint that Bulgarian forces could not easily flank. When Bulgarian armies assaulted the Lines on November 17–18, they were repulsed with heavy casualties. Bulgarian troops were exhausted from weeks of rapid advance, supply lines were stretched to the breaking point, and cholera had begun ravaging the army. A massive Ottoman artillery concentration on elevated ground inflicted devastating losses on attacking Bulgarian infantry. The assault was called off after two days.

The failure at Çatalca saved Constantinople from Bulgarian conquest and preserved the Ottoman dynasty. Had the Bulgarians broken through, they would have reached the Ottoman capital — an event that would have reshaped the entire Near Eastern situation and potentially triggered direct European intervention. The battle demonstrated the limits of the Bulgarian offensive and made a negotiated peace inevitable.

The My Lai revelations fundamentally changed American attitudes toward the Vietnam War and the military, accelerating the anti-war movement and making U.S. withdrawal politically inevitable.
