, commander of the forces defending the White Fathers, who was disrupting the slave trade. By 1891 the slavers had control of the entire western shore of the lake apart from Mpala and the Mrumbi plain. Joubert's position was ambiguous. The Belgians had appointed Tippu Tip as their lieutenant in the region, but Joubert refused to recognize the authority of the slaver. During a lull in January 1891, Father I. Moinet visited Ujiji where he found Rumaliza flying a German flag and saying he was waiting for the Germans to arrive so he could hand over to them. In a letter to Joubert in April 1891, Rumaliza asked if he was employed by the missionaries or by the government of the Congo. Joubert was evasive in his reply, pointing out that Rumaliza sometimes flew the German flag, sometimes the flag of Zanzibar and sometimes that of Britain.

The Congo Free State became stronger and less tolerant of Arab strongmen, determined to stamp them out. By 1892 Rumaliza dominated Tanganyika from his base at Ujiji on the old slave route that led from

on 22 April 1893, finding both towns abandoned. He found a huge supply store at Kasongo including ivory, ammunition, food and luxuries such as gold and crystal tableware. For the next six months Dhanis remained inactive, while Rumaliza's forces were swelled by Swahili fighters who had escaped after defeat by Dhanis.
In 1893 Tippu Tip advised Rumaliza to retire from the trade, but Rumaliza first had to look after his people at Lake Tanganyika. Rumaliza raised a strong force, which clashed with Dhanis' column on 15 October 1893 causing the death of two European leaders and fifty of their soldiers. On 19 October 1893 Rumaliza attacked a position one day's march from Kasongo. Dhanis concentrated his forces and defeated Rumaliza. A column under Captain
Hubert Lothaire pursued him to the north of Lake Tanganyika, destroying his fortified positions along the route. At the lake they joined with the anti-slavery expedition led by Captain
Alphonse Jacques.
By 24 December 1893 Dhanis had obtained reinforcements and was ready to advance again. Rumaliza had also received assistance. Dhanis sent one column under Gillain to prevent Rumaliza from retreating, and another under De Wouters to advance on Rumaliza's fort near Bena Kalunga. A group of fresh forces coming to Rumaliza's aid from Tanganyika was headed off, and Dhanis's forces closed in on Rumaliza's two fortified ''
bomas''. On 9 January 1894 Belgian reinforcements arrived under Lothaire, and the same day a shell blew up Rumaliza's ammunition store and burned down the fort containing it. Most of the occupants were killed while attempting to escape. Within three days the other forts, cut off from water supplies, surrendered. More than two thousand prisoners were taken, although Rumaliza himself managed to escape. Rumaliza took refuge in the German territory of Tanganyika.
