13th Aero Squadron

The 13th Aero Squadron was a Air Service, United States Army unit that fought on the Western Front during World War I.

The squadron was assigned as a Day Pursuit (Fighter) Squadron as part of the 2d Pursuit Group, First United States Army. Its mission was to engage and clear enemy aircraft from the skies and provide escort to reconnaissance and bombardment squadrons over enemy territory. It also attacked enemy observation balloons, and perform close air support and tactical bombing attacks of enemy forces along the front lines. After the 1918 Armistice with Germany, the squadron returned to the United States in March 1919 and demobilized.

On 16 October 1936 the squadron was re-constituted, and consolidated with the United States Army Air Corps 13th Attack Squadron. Today, the current United States Air Force unit which holds its lineage and history is the 13th Bomb Squadron, assigned to the 509th Operations Group, Whiteman Air Force Base, Missouri.

Origins
The 13th Aero Squadron was organised at Kelly Field, Texas on 14 June 1917. After a short period of organization, which included "snake-chasing and cactus-cutting", the squadron was moved to Wilbur Wright Field, Ohio in the beginning of July where its aviation cadets began flight training on the Curtiss JN-4 Jenny trainer. Training in Ohio lasted until 1 November when it received orders for overseas duty. The squadron proceeded to the Aviation Concentration Center, Garden City, New York, where it awaited transport to Europe. At the end of November, the squadron moved to Philadelphia, where it boarded the SS Northland, and departed the United States on 4 December. The ship arrived at Liverpool, England on 25 December where the same day, they boarded a train for Winchester, England where they were temporarily assigned to a Rest Camp. After a cross-channel crossing from Southampton to Le Harve, France, the squadron boarded a French train south, arriving at the St. Maixent Replacement Barracks, 1 Jan 1918.

At St. Maixent the squadron waited for several weeks and largely performed construction and other activities designed to improve the newly established base. At the end of January, orders were received to proceed to the 3d Air Instructional Center at Issoudun Aerodrome for advanced flight and air combat training. For the next four months the squadron trained at Issodun, with detachments sent to French Air Force gunnery ranges at Meucon and Haussimont Aerodromes. Finally, in the beginning of June, training was completed and the squadron moved to the 1st Air Depot at Colombey-les-Belles Airdrome where the 13th Aero Squadron was classified as a Pursuit Squadron and received French SPAD XIII aircraft. Once equipped the squadron was ordered to Gengault Aerodrome, near Toul, in the "Zone of Advance". There the 13th received its combat assignment to the 2d Pursuit Group where it joined the 22d, 49th and 139th Aero Squadrons.

Combat in France
The 13th was charged with protection of the St. Mihiel sector, and its pilots soon were active in intercepting and attacking enemy aircraft that attempted reconnaissance over Allied lines. The Spads also escorted Allied observation planes deep into enemy territory where their pilots sometimes engaged enemy planes and attacked hostile balloons.

While participating in the St. Mihiel Offensive, which was undertaken to eliminate the salient in the front lines around St. Mihiel that had existed since early in the war, the 13th fought with vigor. While ground forces were attacking and destroying, men, material, and morale, the 13th's pilots kept busy destroying enemy aircraft and balloons, and making the sky safe for Allied observation planes. The squadron suffered its first combat loss on 13 September when Lt. Robert Converse was shot down on a late afternoon patrol and reported missing in action. On 14 September 1918 a squadron-strength patrol led by Charles Biddle was ambushed by a flight of red and white Fokker D VII aircraft of Jasta 18. Four original squadron members were downed in a matter of minutes: Lt. Charles Drew, Lt Alton Brody, Lt. Harry B. "Buck" Freeman and Lt. George P. Kull. Lts. Converse, Drew, Freeman and Brody were captured and repatriated after the Armistice. George Kull was confirmed killed in action, the first combat fatality of the 13th Aero Squadron.

The Meuse-Argonne campaign was launched on 26 September 1918 to further reduce the St. Mihiel salient. The 13th Aero Squadron moved on 23 September to Belrain Aerodrome, and from there inflicted heavy losses upon enemy aircraft and balloons. As its pilots gained domination of the air, their responsibilities were expanded to include protection of ground forces, strafing of enemy troops and bombing of targets that could be observed within enemy lines. During the Meuse Argonne Offensive, the squadron lost Lts. Gerald D. Stivers, Henry Guion Armstrong, Clarence A. Brodie and Robert H. Stiles killed in action.

On 7 November, the squadron moved to Souilly Aerodrome and continued combat operations until the Armistice with Germany was signed and combat ended on 11 November 1918.

The 13th claimed several "aces" from this period of its history: Charles J Biddle, Murray K Guthrie, Frank K Hays, John J Seerly, and William H Stovall. Major Carl Spaatz, although on orders to return home, sought and received permission to serve with the 13th Aero Squadron as a pursuit pilot. He subordinated himself to men of lower rank, but as a result of his ardent zeal and ability, he was soon a flight leader and was credited with destroying two Fokkers during the St. Mihiel and Meuse-Argonne Offensive.

Demobilization
After the armistice, the squadron remained at Souilly until 16 December 1918 when orders were received from First Army for the squadron to report to the 1st Air Depot, Colombey-les-Belles Airdrome to turn in all of its supplies and equipment and was relieved from duty with the AEF. The squadron's planes were delivered to the Air Service Production Center No. 2. at Romorantin Aerodrome, and there, practically all of the pilots and observers were detached from the Squadron.

Personnel were subsequently assigned to the Commanding General, Services of Supply and ordered to report to the staging camp at Le Mans, France. There, personnel awaited scheduling to report to one of the Base Ports in France for transport to the United States and subsequent demobilization. From 6 February to 3 March 1919, the squadron was at the port of Brest before crossing the Atlantic aboard the SS America. From 13–29 March 1919 the squadron was at Mitchell Field, New York, where it was demobilized. It remained inactive until it was reconstituted in 1936.
