In the French Wikipedia article about Roger de Damas d'Antigny, it is said that this French officer was not satisfied by Austrian armies in the war against Ottoman empire, so he joined the Russian armies against the same opponent.
If I read information about this war of Austrian forces, between 1787 and 1792, the Austrian forces did not achieve significant success against Ottoman forces. Why is that? The source for that is wikipedia, that says:
- "[the Austrian emperor] was a poor strategist"
- "The Ottoman raided the Austrian empperor"
- "Austrian forces suffer losses and did not capture Ottoman territory"
