For one, The Commentaries, which were Caesar's account of his conquest of Gaul. I was actually thinking of getting the audiobook version, the narrator sounds quite goodSorry for the non new episode bump, but listening to Celtic Holocaust and I'd like to read more about Ceaser's military years. Any good books to recommend?

Also if you're new to Hardcore History, you must check out Death Throes of the Republic. Dan explores Caesar's military campaign and life in much more detail
I also enjoyed Caesar by Adrian Goldsworthy and Rubicon by Tom Holland
