During the Boxer Rebellion, Germany ran short of postage at its offices in China. As a result, unoverprinted German stamps and stamps from Kiautschou were used at Feldpost and civilian post offices throughout the territory. The unoverprinted German and Kiautschou stamps used at these offices can be distinguished only by their cancels, and are referred to as “Petschili” issues.

The Petschili issues are generally catalogued in three groups — Krone/Adler Issues, Germania Issues, and Kiautschou Yacht Issues.

The Germania Issues were primarily used at the Shanghai, Tientsin, and Peking post offices, as well as Feldpost offices “a” and “b” within the Ostasiatischen Expeditionscorps (East Asian Expeditionary Corps) and Feldpost Station No. 2, though other lesser-used cancels exist from other stations.

The 2 Pfennig (MiNr. P V z) and 25 Pfennig (MiNr. P V da) values were not among the stocks in the local post offices. They are presumably from the stocks on-board the transport ships that brought German troops to Kiautschou or from the personal possession of individual soldiers. The 2 Pfennig (MiNr. P V z) is extremely common, as 2 Pfenning stamps were common among these alternative sources. The 25 Pfennig (MiNr. P V da) is not, and is the rarest of this set.

Germania dates of use at the Feldpost stations are as follows, though cancels are known as late as 31 December 1902. Those after 31 August 1901 are typically favor cancels.
