strike with the second division from Moschi towards Kondoa Irangi and thence at the German central railway, while the first and third cleared the Pare and Usambara mountains and the coast, and then marched on Handeni and threatened the central railway on a parallel line to Van Deventer's attack. Van Deventer's second division marched with almost incredible speed. He started from Aruscha on 1 April, and by the 19th had driven the Germans from Kondoa Irangi, more than a hundred miles away. In May and June the other divisions cleared the Pave and Usambara mountains, reached Handeni and Kangata, and with naval assistance occupied Tanga, Pangani, Sadani Bay, and Bagamoyo in July and August almost without opposition. Von Lettow-Vorbeck had transferred the bulk of his troops south and then westwards up the central railway to bar Van Deventer's progress; and in the process he had been forced to abandon the north-eastern quarter of the colony. No small part of the north-western province of Ruanda had been lost as well: the Belgians had occupied Kigali and the British had driven the Germans from their shore of Lake Victoria Nyanza. The rapidity and divergence of these attacks, which were admirably timed, distracted Von Lettow-Vorbeck's strategy, and in spite of his interior lines he was unable to offer successful resistance. No sooner did he send troops to bar Smuts' advance from Kangata into the Nguru hills than Van Deventer struck west, south, and south-east from Kondoa Irangi. To the west he took Singida, thus getting behind the Germans on Lake Tanganyika; to the south and south-east he got astride the central railway by 14 July and pushed down it eastwards to Kilossa, which he reached on 22 August. He was now almost due south the Nguru hills, whence Smuts, attacking from the north, had driven the Germans before the middle of August. This converging advance made Mrogoro the only line of retreat, and Smuts planned a complicated outflanking movement to intercept it. They escaped by a track unknown to our forces on the 26th, and prepared to stand south of the central railway in the Ulunguru hills. Smuts was too quick for them, but they repelled a badly-timed attack at Kissaki on 6 September. Their retreat had, however, made the coast untenable: on 3 September the capital Dar-es-Salaam surrendered, and all the remaining ports before the end of the month. Van Deventer, too, had pressed south to the Ruaha on the 10th, the Belgians occupied Tabora on the 19th, and General Northey, advancing from Nyasa in the south-west, had reached Iringa before the end of August, while some Portuguese troops crossed the Rovuma river, the frontier between German East Africa and Mozambique, and made a pretence of marching north. By the end of September the great German colony had been conquered save for the unhealthy south-eastern corner, where only the Mahenge plateau provided a decent habitation for white troops.
