"My dear General,I learn that after long and tough fighting, our brave African troops have captured Tabora, the citadel of the German East African defences.I would like to take advantage of this brilliant feat of arms to offer you, as well as the officers, non-commissioned officers and soldiers under your command, my warmest congratulations on the constant successes won in this far-off campaign which has demanded so much effort to organise."
Beginning of a September 30, 1916 letter from Albert I, King of the Belgians to General Charles Tombeur, senior Belgian officer in Belgian Congo, who had captured Tabora in German East Africa on September 19.
