Latour achieved the rank of a "Generalmajor" in 1782. In the course of the 1789 revolt that led to the proclamation of the autonomous United States of Belgium, Latour was elevated to the rank of a "Feldmarschall-Leutnant". His troops held the Duchy of Luxembourg and played a significant role in regaining the rebellious provinces by the end of 1790, which earned him the Military Order of Maria Theresa. From 1792 onwards Latour fought as an Austrian commander in the Wars of the First and Second Coalition. In 1805 Emperor Francis I of Habsburg appointed him president of the "Hofkriegsrat", Latour nevertheless died shortly afterwards in Vienna.
