On August 27th, 1896, a British battle fleet delivered Said Khalid, the pretender Sultan of Zanzibar, an ultimatum to vacate his palace. When he refused, fighting broke out. Hostilities peaked at 9:15 and ceased at 9:40.
The war was over in 38 minutes, its turning point the sinking of Zanzibar's only warship, the aging Glasgow, with two shells.
As a final insult, local residents were ordered to pay for the ammunition used in the destruction of the Sultan's palace.
