Lists like these are too much coloured by national histories … 😉
I always find it difficult to list ‘decisive’ battles. Battles are not isolated events and have to be considered along with political, societal, and even cultural or scientific events to judge their impact on history. In recent times (the past 200 years or so), and when considering only the military pov, I would even say you cannot look at an individual battle, but should look at an entire campaign or war.
Also, the importance various countries attribute to battles have often more to do with forging a national identity rather than a true historical importance.
But I do think it makes sense to discuss ‘decisive battles’ in the context of the outcome of a specific war or conflict.
