Dufile (also Dufilé, Duffli, Duffle, or Dufli) was originally a fort built by Emin Pasha, the Governor of Equatoria, in 1879; it is located on the Albert Nile just inside Uganda, close to a site chosen in 1874 by then-Colonel Charles George Gordon to assemble steamers that were carried there overland.
Abandoned by Emin's people in January 1889, Dufile being within the Lado Enclave was reoccupied and reconstructed by Belgian forces from 1902 to 1907.
Today the name Dufile is applied to a nearby Madi village and sub-county in Moyo District to the east of Laropi.
There followed the Battle of Dufile when the former mutineers, after releasing Emin and Jephson, rallied to fight Mahdist forces.
The fort, where a ditch and bank enclose an area of 12 acres (4.8 hectares), can be reached by road or boat from Laropi.
