[2] The island was a trading-station on the east bank of the White Nile in Southern Sudan, 1,200 kilometres (750 mi) south of Khartoum.

[4] Gondokoro was the scene for the arrival of John Hanning Speke and James Augustus Grant after their two years and five months long journey through Central Africa from Zanzibar.

... 'Speke', Baker says, 'appeared the more worn of the two: he was excessively lean, but in reality he was in good tough condition; he had walked the whole way from Zanzibar, never having once ridden during that wearying march.

Grant was in honourable rags; his bare knees projecting through the remnants of trousers that were an exhibition of rough industry tailor's work.'"

Other explorers died there, such as Wilhelm von Harnier, Alphonse de Malzac, Alfred Peney and Alexandre Vaudey.
