Shahin's invasion of Asia Minor (615)

In 615, during the ongoing war with the East Roman (Byzantine) Empire, the Sassanid Persian army under spahbod Shahin invaded Asia Minor and reached Chalcedon, across the Bosporus from Constantinople. The Sassanids had already captured Roman Syria and Palestine in the previous year. After negotiations with Byzantine Emperor Heraclius, a Byzantine ambassador was sent to Persian Shahanshah Khosrau II, and Shahin withdrew again to Syria.
