The Union Army Balloon Intrepid being inflated from the gas generators for the Battle of Fair Oaks. Hot air balloons were employed during the American Civil War. [46] The military balloons used by the Union Army Balloon Corps under the command of Prof. Thaddeus S. C. Lowe were limp silk envelopes inflated with coal gas (town gas) or hydrogen.
Balloons and kites were the first inventions used in aerial warfare and their primary role was reconnaissance. Balloons provided a reliable and stable means of elevating an observer high over the battlefield to obtain a birds-eye view of troop positions and movements. An early instrument of aerial intelligence collection, they were also useful ...

A kite balloon is a tethered balloon which is shaped to help make it stable in low and moderate winds and to increase its lift. It typically comprises a streamlined envelope with stabilising features and a harness or yoke connecting it to the main tether and a second harness connected to an observer's basket.
Balloons are often deliberately released, creating a so-called balloon rocket. Balloon rockets work because the elastic balloons contract on the air within them, and so when the mouth of the balloon is opened, the gas within the balloon is expelled out, and due to Newton's third law of motion, the balloon is propelled forward. This is the same ...
The corps transporting the balloon to Fleurus. In May 1794, the new corps joined Jourdan's troops at Maubeuge, bringing one balloon: L'Entreprenant. They began by constructing a furnace, then extracting hydrogen. [3] The first military use of the balloon was on 2 June, when it was used for reconnaissance during an enemy bombardment. [2]
Other defenses included surrounding the main balloon with barrage balloons; stringing cables in the air in the vicinity of the balloons; equipping observers with machine guns; and flying balloons booby-trapped with explosives that could be remotely detonated from the ground. These measures made balloons very dangerous targets to approach. [1]
