 In addition to the smaller @-@ scale expeditions described earlier , Mathews embarked on two much larger expeditions to the African mainland during his tenure as first minister , the first at Mwele . The initial rebellion in the area had been led by Mbaruk bin Rashid at Gazi , which Mathews had put down with 1 @,@ 200 men in 1882 . However , in 1895 Mbaruk 's nephew , Mbaruk bin Rashid , refused to acknowledge the appointment of a new leader at <unk> . This led to open rebellion at <unk> in February of that year when the younger Mbaruk attacked Zanzibari troops under Arthur <unk> , one of Mathews ' officers . Mathews was part of an Anglo @-@ Zanzibari expedition sent to quell it , which consisted of 310 British sailors , 50 Royal Marines , 54 Sudanese and 164 Zanzibari troops . <unk> was destroyed and the leaders fled to Gazi where the older Mbaruk failed to turn them over . Another force , under Admiral Rawson , with 400 British marines and sailors , was sent after them . This further expedition failed to capture the <unk> and a third expedition was organised by Rawson with 220 sailors , 80 marines , 60 Sudanese and 50 <unk> , which destroyed Mwele . During the latter action Mathews was wounded in the shoulder .
