Battle of Dorylaeum
First Crusade · Dorylaeum (present-day Eskişehir, Türkiye)
Summary
On July 1, 1097, the column of Bohemond and Robert of Normandy, loaded with baggage, was attacked near Dorylaeum by the horsemen of Kilij Arslan and the Danichmendide emir. The Turks surrounded the crusaders and harassed their lines until the arrival of Godfrey of Bouillon, Raymond of Saint-Gilles and Hugh of Vermandois who, after a forced march, reached the enemy rear. Stuck between two masses of heavy cavalry, the Turkish army disbanded and abandoned its camp. Albert of Aix losses (~4,000 / ~3,000) preferred to the corpus “10,000” Turks; John France stresses imprecision (English Wikipedia).
Historical context
The crusader leaders decided to advance in two spaced columns to facilitate resupply. Kilij Arslan wants to exploit this dispersion by crushing the Norman vanguard before the rest of the army intervenes. Bohemond forms a defensive circle around the chariots, protecting pilgrims and non-combatants. Reinforcements arrive thanks to the scouts sent at full speed by Robert of Flanders.

Tactics
English Wikipedia Battle of Dorylaeum (1097) / First Crusade notes: 1 July 1097 near Dorylaion (Eskişehir). Advance column (Bohemond, Robert Curthose) attacked by Kilij Arslan’s mounted archers. Tight defensive formation around non-combatants and baggage; costly small countercharges. Relief from the second column (Godfrey, Raymond, legate Adhemar): breakthrough and outflanking; Turks withdraw. Albert of Aix: ~4,000 / ~3,000 losses (not “10,000” Turks). Victory opening the Anatolian march toward Antioch.
Consequences
The victory at Dorylaeum definitively breaks the Seljuk capacity to block the road to Anatolia: Kilij Arslan abandons his cities, which are pillaged by the crusaders during their advance. Latin morale soars and the experience acquired against the Turkish cavalry influences the tactics used later at Antioch and Ascalon.
