The Battle of Bukoba was the first victory for Entente forces in German East Africa, coming after the disastrous battles of Tanga and Jassin. The British objective was the destruction of the Bukoba wireless station. Due to Bukoba's location on the shore of Lake Victoria, it was decided that the raid should take the form of an amphibious assault.

The Battle of Jassin was a World War I battle that took place on 18– 19 January 1915 at Jassin on the German East African side of the border with British East Africa between a German Schutztruppe force and British and Indian troops. Jassin had been occupied by the British in order to secure the border between British East Africa and German territory, but was weakly defended by a garrison of four companies of Indian troops, commanded by Colonel Raghbir Singh and numbering a little over 300 men. Colonel Raghbir Singh was killed during the battle.

The Battle of Kahe was fought during the East African Campaign of World War I. It was the last action between German and Entente forces before the German retreat from the Kilimanjaro area. British and South African forces surrounded German positions at Kahe, south of Mount Kilimanjaro. Entente forces inflicted heavy casualties and captured large German artillery pieces while receiving comparably little casualties. German forces retreated from there, further into the interior of the colony.

The Battle of Kibata was fought north-west from Kilwa during the East African Campaign of World War I. The British theatre commander, South African General Jan Smuts, planned to seize Kibata and prevent German forces from withdrawing southwards.

The Battle of Kidodi was fought during the East African Campaign of World War I.

The Battle of Kilimanjaro at Longido took place in German East Africa in November 1914 and was an early skirmish during the East African Campaign of the First World War.

The Battle of Latema Nek was a battle of the East African Campaign in World War I.

The Battle of Lioma was fought between the German Empire and British Empire during the East African Campaign of World War I. Having successfully evaded the Allies since late 1917, the German Schutztruppe under Paul von Lettow-Vorbeck waged a guerilla campaign in Portuguese East Africa, attacking and raiding settlements as well as forts in the search of supplies while inflicting as much damage as possible on the Allies. All the while, the Schutztruppe was chased by the British King's African Rifles, which finally cornered the Germans at the village of Lioma on 30–31 August 1918. Led by George Giffard, the British forces almost managed to encircle and destroy the Schutztruppe, but in the end the Germans broke out and successfully retreated. Although greatly weakened by the fighting at Lioma, the Schutztruppe was thus able to remain active until the end of the war.

The Battle of Mahiwa between German and British Imperial forces was fought during the East African Campaign of World War I, when South African and Nigerian troops under Lieutenant General Jacob van Deventer engaged a column under German General Paul Emil von Lettow-Vorbeck, at Mahiwa in German East Africa. The Germans inflicted substantial casualties upon Van Deventer's army, forcing it to withdraw. But the Germans lost a large percentage of their forces, and were ultimately forced to withdraw from their positions and continue their guerrilla war. The battle was noted as, by the British Official History, as the "Most disastrous day for the Nigerian Army since the formation of the force" and was called "The most savage battle in the history of African conflict-not excluding Omdurman or any engagement of the Boer War."

The Maziua raid was an armed clash between German and Portuguese colonial troops in Mozambique on 24 August 1914 during World War I. Though the two countries were officially at peace, German soldiers carried out a cross-border raid into Portuguese Mozambique for unclear reasons, and destroyed the outpost of Maziua. The Portuguese soldiers killed in the raid were the first Portuguese casualties of World War I.

The Battle of Ngomano or Negomano was fought between Germany and Portugal during the East African Campaign of World War I. A force of Germans and Askaris under Paul Emil von Lettow-Vorbeck had recently won a costly victory against the British at the Battle of Mahiwa, in present-day Tanzania and ran very short of food and other supplies. As a consequence, the Germans invaded Portuguese East Africa to the south, both to supply themselves with captured Portuguese materiel and escape superior British forces to the north.

The Battle of Salaita Hill was the first large-scale engagement of the East African Campaign of the First World War to involve British, Indian, Rhodesian, and South African troops. The battle took place on February 12, 1916, as part of the three-pronged offensive into German East Africa launched by General Jan Smuts, who had been given overall command of the Allied forces in the region.

The Battle of Tanga, sometimes also known as the Battle of the Bees, was the unsuccessful attack by the British Indian Expeditionary Force "B" under Major General A.E. Aitken to capture German East Africa during the First World War in concert with the invasion Force "C" near Longido on the slopes of Mount Kilimanjaro. It was the first major event of the war in Eastern Africa and saw the British defeated by a significantly smaller force of German Askaris and colonial volunteers under Lieutenant Colonel Paul von Lettow-Vorbeck. It was the beginning of the East African Campaign of World War I, and is considered one of greatest victories of the Schutztruppe in Africa. The British retreat enabled the Schutztruppe to salvage modern equipment, medical supplies, tents, blankets, food and a number of Maxim Machine Guns which allowed them to successfully resist the allies for the rest of the War.
