Most Sudanese slaves gathered for the army died before reaching Egypt

Evidence

The Sudan campaign had so far yielded mixed results. While Ismail Pasha, and later Mehmed Bey Defterdar, were able to gather a significant number of slaves and send them to Egypt, a lot of them either perished on the way or proved incapable of bearing arms. Out of 20,000 slaves gathered between 1820 and 1824 only 3,000 remained alive in 1824. — Khaled Fahmy, All the Pasha_s Men_ Mehmed Ali, his…, 453
