Uganda protectorate assaulted German river outposts near Lake Victoria. On the same day, the British War Cabinet ordered an Indian Expeditionary Force (IEF) to be sent to East Africa to eliminate bases for raiders. On 8 August, the Royal Navy cruiser shelled the wireless station at Dar es Salaam, then agreed a ceasefire, on condition the town remained an open city. This agreement caused discord between Vorbeck and Governor Heinrich Schnee, his nominal superior, who opposed and later ignored the agreement; it also caused the captain of Astraea to be reprimanded for exceeding his authority.

On 15 August, Askari in the Neu Moshi region engaged in their first offensive operation of the campaign. Taveta on the British side of Kilimanjaro fell, to two companies of Askari (300 men) with the British firing a token volley and retiring in good order.

The British armed the Uganda Railway lake steamers , , and as improvised gunboats; the tug was trapped and then scuttled by the Germans. The Germans later raised Kingani, dismounted her gun and used the tug as a transport; with the tug disarmed and her "teeth removed, British command of Lake Victoria was no longer in dispute."
