Cahill Galligan was raised in County Clare within sight of the great stone forts of the Burren, an upbringing that left him with a lifelong fascination for fortifications and the empires that built and broke them. He studied ancient and medieval history before turning to independent research into the late Roman and Sasanian world, with particular interest in the campaigns of Justinian's generals and the diplomatic settlements that followed them.
Galligan approaches military history as a study of human judgment under pressure - how commanders absorb failure, adapt, and occasionally produce moments of genuine brilliance. This is his latest work of narrative nonfiction exploring the wars of late antiquity, written for readers who want the precision of scholarship and the pace of a story well told.
