They passed a letter from Boqor Osman that was meant for the Ottoman empire to Italian Minister in Cairo.
It's never your enemies that get you. It's always your own people.
The north-eastern sultanates of Majeerteen and Hobyo developed a very effective political organization with diversified measures of centralized authority over relatively large territories. Italy, Britain, Germany and France had been trying to solicit them into their sphere of influence since the early days of their competition for the Somali peninsula. In the closing decades of the 1880s Germany was the first colonial power to have built a special relationship with the Majeerteen.
The matter worried Italy and it reasoned that unless Boqor Osman was brought under their directive they feared they could not control the sultanate. Misunderstanding and distrust was in the making. The conflict of interest was leading to confrontation as each side began accusing the other.
Whilst the situation was still in confusion, the Italian Minister in Cairo intercepted a letter from Boqor Osman seeking Ottoman protection over what the latter termed the "Independent Majeerteen Somali". Furthermore, Italy learned about the sultanate's arms build-up. Before it was too late, Italy decided to breach the treaty and to bring Boqor Osman to his knees. The Volta ship bombarded the coastal villages of Bareeda and Bender Khassim (Boosaaso), crippling the sultanate's modest arms and ammunition warehouses. Boqor Osman fled to the interior, while Italian troops captured the sea towns of Alula, Bender Khassim, Bareeda and Muranyo. Boqor Osman had been taken by surprise, and had attempted unsuccessfully to counter the Italians in too many battlefields.
Things were further complicated by other developments in the region: the Italo-British arrangements for confining the Daraawiish to the Nugaal area was growing untenable. The British had failed to secure peace with the Daraawiish and were in retreat. The good relationships which in the past Boqor Osman had had with Sayid Mahamed ended after persistent Daraawiish scorched earth raids on Majeerteen settlements. Initially Boqor Osman had repulsed invasions of his Sultanate by the Daraawiish. But armed confrontation with the Italians had made him vulnerable to the Daraawiish attacks. He turned to the Italians for an "honourable settlement".
By 1st October, De Vecchi's plan was to go into action. The operation to invade Hobyo started in October 1925. Columns of the new Zaptié began to move towards the sultanate. Hobyo, El-Buur, Galkayo, and the territory between were completely overrun within a month. Hobyo was transformed from a sultanate into an administrative region. Sultan Yusuf Ali surrendered. Nevertheless, soon suspicions were aroused as Trivulzio, the Hobyo commissioner, reported movement of armed men towards the borders of the sultanate before the takeover and after. Before the Italians could concentrate on the Majeerteen, they were diverted by new setbacks. On 9 November, the Italian fear was realised when a mutiny, led by one of the military chiefs of Sultan Ali Yusuf, Omar Samatar, recaptured El-Buur. Soon the rebellion expanded to the local population. The region went into revolt as El-Dheere also came under the control of Omar Samatar. The Italian forces tried to recapture El-Buur but they were repulsed. On 15 November the Italians retreated to Bud Bud and on the way they were ambushed and suffered heavy casualties.
