You're going to need to specific about a place/period or fortification system. Even then, I may not know the technical works. For an overview of Roman forts, Luttwak, Grand Strategy of the Roman Empire has a good cross-period comparison for a newcomer to the topic.
Honestly, apart from gunpowder weapons, books that look at a given military phenomenon over a lot of different cultures and time periods at any level of scholarly rigor are rare. Unless you are K. Chase or T. Andrade, nobody has those kinds of language skills.
