Battle of Gatae
There is no serious historical evidence giving an exact place or time to the battle, nor any troop positions, numerical statistics, casualties, or much of anything of that nature. It is not even fully understood if the battle was in of itself a major engagement or merely a small battle or even a large skirmish. Dio Cassius gives a minor mention of the battle, but it is a mere mention.
It is understood that this battle did, however, somehow break the back of the Dacian army and allow the Roman Legions to make serious tactical headway. However, Decebalus, king of Dacia, managed to secure a peace before the capital of Sarmizegetusa was captured.
