The treatise How to Survive Under Siege by Aineias Tacticus, is among the earliest treatises to survive from the genre of didactic military literature. Its author was regarded as the pre-eminent authority on military science in subsequent centuries because he wrote many other works. None of these survive. This single surviving treatise (although incomplete) covers nearly everything that a city need do in order to survive a siege by an enemy. Dur: 24mins File: .mp3
