Background and detail

Strategic Context. The Hexamilion wall guarded the Isthmus of Corinth, the sole land route to the Peloponnese. Following Ottoman breaches in 1423, 1431, and 1446, the Byzantine Despotate of the Morea remained a precarious vassal state, dependent on tribute payments to maintain its independence.

The 1452 Invasion. Turahan Bey led a large force into the peninsula in early October 1452. He stormed the Hexamilion defenses and raided extensively from Corinth through the Argolid and Arcadia to Messenia. The Byzantines offered minimal resistance, though Turahan's son Ahmed was captured in an ambush at Dervenakia.

Strategic Impact. Mehmed II ordered Turahan to remain in the region through the winter to prevent the Moreot despots from aiding Emperor Constantine XI during the 1453 siege. This containment strategy was intended to isolate Constantinople from potential relief forces from the Peloponnese.
