August a flotilla anchored off Bagamoyo that included Vengeance, the protected cruiser , the monitors and , the armed merchant cruiser , and several auxiliary ships. The Royal Navy landed a force of 176 armed sailors, 65 Royal Marines and 55 Zanzibar Rifles to attack the town. A kite balloon flown by directed a naval bombardment of German positions ashore. A seaplane from Himalaya bombed German trenches in the town, and then assisted in directing naval gunnery. The Imperial German Army defended Bagamoyo with 60 German troops and 350 Askari Schutztruppe, commanded by German officers. However, many of the defenders were at Mtoni, about west of Bagamoyo, defending a crossing over the Kingani River. The German defences of Bagamoyo included trenches along the shore, around the Arab and German forts, and on a hill just south of the town. German artillery included at least two small field guns on the shore, plus one of the 105 mm naval guns that had been salvaged from the cruiser , and installed in an emplacement on the hill with 100 rounds of ammunition. Königsbergs gun engaged the monitors Severn and Mersey, which were some distance out to sea, but it could not be lowered enough to engage vessels nearer the shore. Three smaller Royal Navy vessels, including the armed tugboat , got within 500 metres of the German gun and opened fire on it with their 3-pounder guns. A British machine gun section then attacked the hill, eventually forcing the German artillerymen to abandon their gun and retreat. This was the first of Königsbergs guns to be captured by British forces. Many civilians, whatever their religion, took refuge in the church at the Catholic mission. One British 12-inch shell hit the church, damaging the baptistry, and the two priests in charge of the mission moved the civilians to the Mission House. By the evening, German forces were retreating from their trenches. Royal Marines, supported by Zanzibar Rifles, captured the German Governor's house. The remainder of the town fell to British forces thereafter. British forces lost one Royal Marine officer and ten men. German forces lost two officers and ten men, and another 19 were captured by the British.
