were still forming. A truck was assigned to each squadron, along with a fifth truck serving as a mobile workshop. Each squadron had a commander, five pilots, and six observers, with all officers seconded from parent units. As a result, most of the new aviators were from the Engineers and Artillery components of the Belgian armed forces. As the war began, a fifth squadron was created, staffed with civilian pilots called to the colors and equipped with Bleriots. Henri Crombez flew one of the first war patrols, in a Deperdussin racer on 4 August 1914 above Liège. Adjutant Behaeghe was the first to engage an enemy, a few days later. On 26 September, the Belgian air crew of de Petrowski and Sergeant Benselin mortally wounded a German pilot with a rifle bullet and forced his Taube to land at Sint-Agatha-Berchem; if they had submitted a claim for this victory, its approval would have marked history's first air-to-air combat victory. On 3 January 1915, two machine guns supplied by British were fitted to two Belgian aircraft, making a dual effort against the foe possible; these were Belgium's first dedicated fighter planes. In February, thirteen of the Belgian airmen flew 28 offensive patrols; their first dogfight was fought on the 26th, with ten Albatroses against three Belgian Farmans. On 26 March, Boschmans sent a German two-seater into a steep dive when he seemed to hit the pilot; the German was not seen to either crash or land. This was the Belgian aviators' first victory claim. In April, Lieutenant Fernand Jacquet mounted a machine gun on his pusher aircraft and sought out the enemy. On the 17th, he and his observer (Lieutenant Henri Vindevoghel) scored Belgium's first confirmed aerial victory, sending an Albatros reconnaissance aircraft down in flames over Roeselare. Apparently at about the same time, Adjutant José Orta and Louis de Burlet were the first to attack an enemy observation balloon when they dropped three small bombs on a gasbag over Houthulst, however they either did not hit, or failed to explode. On 18 January 1916, the decision was made to form a dedicated fighter squadron. On 22 February 1916, Escadrille I became the . It consisted of newly supplied Nieuport 10s and one obsolete Farman two-seater. In August, the new squadron would upgrade to Nieuport 11s, and was turned into the . The new unit was the first to mount an
