Explanation:

When the first practical aircraft were produced, in the form of hot-air and hydrogen balloons in 1783, they were adopted quickly for military duties. In 1793 the French National Convention authorized formation of a military tethered-balloon organization, and a company of “Aérostiers” was formed on April 2, 1794. Two months later the first military reconnaissance from such a balloon was made before the city of Maubeuge. Until the Aérostiers were disbanded in 1799, their reports contributed to the success of French armies in many battles and sieges. Similar reconnaissance balloons were used later by other armies, notably by both armies during the American Civil War and by the British in Africa from 1884 to 1901.
