Siege of Senonae

In 356 AD, Roman Emperor Julian the Apostate over-wintered in Senonae (possibly modern Sens) in Gaul. Following desertions from his German federated troops, hostile Germanic warbands learned that his force was under-strength and moved to attack the town. However, they were not able to break into the town, lacking advanced siegecraft, and could only prevent Julian from venturing outside the walls. After a month, they withdrew.
