Bonjour Hagar!
Interesting photographs ... it is unfortunate that memories of your grandfather remain untold.
The 8th Balloon Company was formed on the 4th of November, 1917 at Fort Omaha in Nebraska and the unit became operational on the 8th of February, 1918 with the commanding officer Lieutenant M.L. Witherup. Sent to the field as a training unit at Cuperly, the 8th Balloon Company was forced to abandon the facilities by German forces and was moved about; to Romilly-sur-Seine, Marigny-le-Chatel, Haussimont, La Courtine and then to Royameix and worked with the 4th Army Corps.
The balloon, operated by Cleo J. Ross and Harvey Holland, was attacked three times and sustained damage on each occasion and eventually had to be scrapped.
The majority of the balloon companies were concentrated in the Toul area to support the offensive of St. Mihiel. The 8th Balloon Company moved to Rattantout prior to arriving at Recicourt. The unit was to follow the advance of the 1st Army, 5th Army Corps and did not stay in one location for more than a few days.
On September 26, operating in the vicinity of Brabant-en-Argonne Ross and Herbert B. Hudnut, while aloft were attacked and the balloon was set afire. Both men jumped, but, debris from the balloon set the parachute of Ross alight while Hudnut was able to land safely. Ross was to be the only balloon observer to be killed by enemy action and was awarded the Distinguished Service Cross posthumously while Hudnut was fortunate to survive.
Apparently the balloon was destroyed by a pilot by the name of Hebler who flew with Jasta 68 for the third of three victories confirmed, all of which were balloons, two being downed that day: September 26.
By the end of October the unit was at Montfaucon, with three other balloon companies, and while there another balloon was destroyed from which the observer Arthur Stubbs was able to parachute to safety.
On November 6 Witherup left the unit to take command of the 9th Corps Balloon Group and Lieutenant Hollis H. Jennings took command.
If you develop "balloon fever" Hagar I can recommend the following books -
Balloon-Busting Aces of World War 1 by Jon Guttmann - a history of the airmen who sought to down balloons during The Great War.
The Balloonatics by Alan Morris - an interesting overview of balloon operations and operators throughout The Great War
Wings of Honor by James J. Sloan, Jr. - a history of American airman in The Great War including detail of balloon operations.
America's First Eagles - something of an official history of the United States Air Service from 1917 to 1918 with information about balloon operations.
Thank you for the posting.
Salut!
