1000 Piastres Siege of Khartoum

Gordon issued these notes inside besieged Khartoum from March 1884 onward, as the Mahdist forces cut off all external supply and the city's treasury ran dry. They are among the very few examples in banknote history of a military commander personally signing emergency currency into existence under active siege conditions — Gordon's signature appears on each note as both authorization and guarantee, backed by nothing more than the promise of a relief column that never arrived in time.

Printed locally with whatever materials were available, the notes circulated within the city walls until the fall of Khartoum on 26 January 1885, when Gordon was killed. Survivors who escaped with notes had no issuing authority left to redeem them.
