Siege

The fortifications of Singara—including its moat, both outer and inner walls, and projecting towers—clearly reflected the style of late Roman and early Byzantine military architecture, built to withstand well-equipped siege attacks.^[4] Roman historian Ammianus Marcellinus describes the Sassanian siege in 360, during which a massive battering ram finally brought down a round tower that had only recently been repaired.^[4] This led to the capture of Singara.^[4]

The 1st Flavian and 1st Parthian legions which had formed the garrison, as well as the inhabitants of Singara, were sent into captivity in Sasanid Persia.^[2][3]
