Mobilisation The United Kingdom declared war on Germany on 4 August 1914, following the invasion of Belgium. The Uganda KAR battalion was mobilised for service outside the territory, leaving the defence of Uganda in the hands of the UVR, the local police and the KAR Reserve of retired ex-soldiers. The government amended the Ordinance on 11 August to allow greater flexibility in its deployment of the UVR; the requirement for two days' notice prior to call-up for service was removed and secretaries were no longer permitted to except members from duty or appoint officers, these roles falling to the governor. The new Ordinance brought the UVR under military law (in times of war only) for the first time. The first government-appointed officers were installed on 20 August. These included the acting commissioner of the
Uganda Protectorate Police as commandant and the assistant district commissioner of Entebbe as adjutant. From 22 August authorisation was granted to pay members of the UVR who were called up, including those receiving training, though no uniform was implemented. On 24 August the UVR was reformed as an infantry battalion of three companies. No. 1 Company consisted of the Entebbe Corps, No. 2 Company the Kampala Corps and No. 3 Company (also based at Kampala) was to accommodate members of Indian ethnicity who were joining the reserve in increasing numbers. The European UVR members were of British, French, Dutch, Boer, Danish, Scandinavian, Greek and Armenian origin. Those with citizenship of neutral countries were placed into class 2b only. No. 3 Company consisted largely of former Punjabi soldiers of the
British Indian Army, mainly Sikhs with a number of Hindus and Muslims. Some 3,000 of these levies were mobilised during the war, together with 15,000 held in reserve. They patrolled alongside the police on the southern frontier. Revolts were also incited by the Germans among the African residents of Southern Uganda. British forces on this front were supported by Belgian troops from September 1914. A "striking force" was established within the UVR at Kampala, with members reporting daily to headquarters to carry messages. There was also a proposal to deploy 50 of the Indian members as a separate unit and a special training course was started in Kampala, before the idea was dropped. On 5 September 1916 the governor of Uganda,
Sir Frederick Jackson, sent a letter of thanks to the commandant of the UVR for the unit's service during the war. In December 1916 Jackson recommended to the secretary of state for the colonies that several officers be commended for their service. Three officers, Captain (local Major) F.A. Flint, Captain (local Major) E. H. T. Lawrence and Captain (local Lieutenant Colonel) C. Riddick, were subsequently named in a commendation notice issued by the War Office on 7 August 1917. All members of the UVR that were called up were entitled to the
British War Medal. A former orderly sergeant in the UVR published a book,
The Uganda Volunteers and the War, in 1917 that detailed some of the war-time activities of the unit. == Post-war and disbandment ==
