Heavy cannonball made of iron. The object was donated to the Gewerbemuseum Ulm by military hospital inspector Jakob Keidel in 1919. Keidel was stationed in the Tianjin (Tientsin) field hospital from 1900/1901 with the garrison of the East Asian Expeditionary Corps, from 1901 the East Asian Occupation Brigade, and was thus involved in the military operations of the German Empire in the Boxer War. During his two-year stay in China, he collected various objects, including Chinese clothing and tools or bullets from the context of the fighting. He acquired the objects by purchasing them from Chinese traders or as gifts, among other things. He donated or loaned a selection from his collection to the Gewerbemuseum Ulm in several stages. The cannonball was presented to Keidel as a memento in 1901. It is said to have come from the siege of the former Peitang Monastery (Peitang Fort) in the north of Beijing by the Boxers, who had fired it at the monastery grounds in 1900. On 27 August 1901, during a visit to the monastery, the superior of the monastery presented the bullet to Keidel as a memento.
