It is located on the heights of the confluence of the Aisne and the Vesle near the communes of Condé-sur-Aisne and Chivres-Val.
Eupterornis from the Paleocene of Châlons-sur-Vesle (France) has some features reminiscent of loons, but others seem more similar to Charadriiformes such as gulls (Laridae).
Its flow was recorded over a period of 34 years (1967-2000), at Braine, in the department of Aisne.
In the retreat during Operation Michael in March 1918 his efforts resulted in a bar to his DSO, and during the Third Battle of the Aisne he won his VC for inspiring the defence of a hill above the River Vesle at Jonchery during 27–29 May 1918.
Reaching the Aisne in under six hours, the Germans smashed through eight Allied divisions on a line between Reims and Soissons, pushing the Allies back to the river Vesle and gaining an extra 15 km of territory by nightfall.
