The African theatre of the First World War comprises campaigns in North Africa instigated by the German and Ottoman empires, local rebellions against European colonial rule and Allied campaigns against the German colonies of Kamerun, Togoland, German South West Africa, and German East Africa. The campaigns were fought by German Schutztruppe, local resistance movements and forces of the British Empire, France, Italy, Belgium, and Portugal.
Background
Strategic context
German colonies in Africa had been acquired in the 1880s and were not well defended. They were enclosed by territories controlled by Britain, France, Belgium and Portugal. Colonial military forces in Africa were relatively small, poorly equipped and had been created to maintain internal order, rather than conduct military operations against other colonial forces. The Berlin Conference of 1884 had provided for European colonies in Africa to be neutral if war broke out in Europe; in 1914 none of the European powers had plans to challenge their opponents for control of overseas colonies. When news of the outbreak of war reached European colonialists in Africa, it was met by little of the enthusiasm seen in the capital cities of the states which maintained colonies. An editorial in the East African Standard on 22 August argued that Europeans in Africa should not fight each other but instead collaborate to maintain the repression of the indigenous population. War was against the interest of the white colonialists because they were small in number, many of the European conquests were recent, unstable and operated through existing local structures of power; the organisation of African economic potential for European profit had only recently begun.
In Britain, an Offensive sub-committee of the Committee of Imperial Defence was appointed on 5 August and established a principle that command of the seas was to be ensured and that objectives were considered only if they could be attained with local forces and if the objective assisted the priority of maintaining British sea communications, as British Army garrisons abroad were returned to Europe in an "Imperial Concentration". Attacks on German coaling stations and wireless stations were considered to be important to clear the seas of Imperial German Navy commerce raiders. The objectives were at Luderitz Bay, Windhoek, Duala and Dar-es-Salaam in Africa and a German wireless station in Togoland, next to the British colony of Gold Coast in the Gulf of Guinea, which were considered vulnerable to attack by local or allied forces and in the Far East, which led to the Siege of Tsingtao.
North Africa
Zaian War, 1914–1921
Attempts were made by the German Empire and the Ottoman Empire to influence conditions in the French colonies by intriguing with the potentates who had been ousted by the French. Spanish authorities in the region informally tolerated the distribution of propaganda and money but thwarted a German plot to smuggle 5,000 rifles and 500,000 bullets through Spain. The Teskilat-i Mahsusa maintained several agents in North Africa but had only two in Morocco. The Zaian War was fought between France and the Zaian confederation of Berber people in French Morocco between 1914 and 1921. Morocco had become a French protectorate in 1912 and the French Army extended French influence eastwards through the Middle Atlas mountains towards French Algeria. The Zaians, led by Mouha ou Hammou Zayani quickly lost the towns of Taza and Khénifra but managed to inflict many casualties on the French, who responded by establishing groupes mobiles, combined arms formations of regular and irregular infantry, cavalry and artillery. By 1914 the French had 80,000 troops in Morocco but two-thirds were withdrawn from 1914 to 1915 for service in France and at the Battle of El Herri (13 November 1914) more than 600 French soldiers were killed. Hubert Lyautey, the governor, reorganised his forces and pursued a forward policy rather than passive defence. The French regained most of the lost territory, despite intelligence and financial support from the Central Powers to the Zaian Confederation and raids which caused losses to the French when already short of manpower.
Senussi campaign, 1915–1917
Before 1906, when the Senussi became involved in resistance against the French, they had been a "relatively peaceful religious sect of the Sahara Desert, opposed to fanaticism". In the Italo-Turkish War (29 September 1911 – 18 October 1912) Italian forces occupied enclaves along the Libyan coast and the Senussi resisted from the interior, maintaining generally friendly relations with the British in Egypt. In 1913, the Italians had been defeated at the action of Etangi but in 1914 Italian reinforcements led to a revival and by January the Senussi were in south-eastern Cyrenaica. The Senussi had about 10,000 men armed with modern rifles, with ammunition from a factory which produced 1,000 rounds a day. Intermittent fighting continued between the Italians in fortified towns and the Senussi ranging through the desert. The British declared war on the Ottoman Empire on 5 November and the leadership of the Ottoman Empire encouraged the Senussi to attack Egypt from the west. The Ottomans wanted the Senussi to conduct operations against the rear of the defenders of the Suez Canal; the Ottomans had failed in previous attacks against British forces from Sinai in the east and wanted them to be distracted by attacks from the opposite direction.
Coastal campaign, 1915–1916
On 6 November, the German submarine U–35 torpedoed and sank a steamer, HMS Tara, in the Bay of Sollum. U-35 surfaced, sank the coastguard gunboat Abbas and badly damaged Nur el Bahr with its deck gun. On 14 November the Senussi attacked an Egyptian position at Sollum and on the night of 17 November, a party of Senussi fired into Sollum as another party cut the coast telegraph line. Next night a monastery at Sidi Barrani, 48 mi (77 km) beyond Sollum, was occupied by 300 Muhafizia and on the night of 19 November, a coastguard was killed. An Egyptian post was attacked 30 mi (48 km) east of Sollum on 20 November. The British withdrew from Sollum to Mersa Matruh, 120 mi (190 km) further east, which had better facilities for a base and the Western Frontier Force (Major-General A. Wallace) was created. On 11 December, a British column sent to Duwwar Hussein was attacked along the Matruh–Sollum track and in the Affair of Wadi Senba, drove the Senussi out of the wadi. The reconnaissance continued and on 13 December at Wadi Hasheifiat, the British were attacked again and held up until artillery came into action in the afternoon and forced the Senussi to retreat.
The British returned to Matruh until 25 December and then made a night advance to surprise the Senussi. At the Affair of Wadi Majid, the Senussi were defeated but were able to withdraw to the west. Air reconnaissance found more Senussi encampments in the vicinity of Matruh at Halazin, which was attacked on 23 January, in the Affair of Halazin. The Senussi fell back skilfully and then attempted to envelop the British flanks. The British were pushed back on the flanks as the centre advanced and defeated the main body of Senussi, who were again able to withdraw. In February 1916, the Western Frontier Force was reinforced and a British column was sent west along the coast to re-capture Sollum. Air reconnaissance discovered a Senussi encampment at Agagia, which was attacked in the action of Agagia on 26 February. The Senussi were defeated and then intercepted by the Dorset Yeomanry as they withdrew; the Yeomanry charged across open ground swept by machine-gun and rifle fire. The British lost half their horses and 58 of 184 men but prevented the Senussi from slipping away. Jafar Pasha, the commander of the Senussi forces on the coast, was captured and Sollum was re-occupied by British forces on 14 March 1916, which concluded the coastal campaign.
Band of Oases campaign, 1916–1917
On 11 February 1916 Ahmed Sharif as-Senussi, leader of the Senussi order in Cyrenaica, occupied Bahariya Oasis in Giza, which was then attacked by British Royal Flying Corps bombers. Farafra Oasis was occupied at the same time and then the Senussi moved on to Dakhla Oasis on 27 February. The British responded by forming the Southern Force at Beni Suef. Egyptian officials at Kharga Oasis were withdrawn and the oasis was occupied by the Senussi until they withdrew without being attacked. The British reoccupied the oasis on 15 April and began to extend the light railway terminus at Kharga to the Moghara Oasis. The mainly Australian Imperial Camel Corps patrolled on camels and in light Ford Motor Company cars to cut off the Senussi from the Nile Valley. Preparations to attack Bahariya Oasis were detected by the Senussi garrison, which withdrew to Siwa in early October. The Southern Force attacked the Senussi in the Affairs in the Dakhla Oasis (17–22 October), after which the Senussi retreated to their base at Siwa.
In January 1917, a British column including the Light Armoured Car Brigade with Rolls-Royce Armoured Cars and three Light Car Patrols was dispatched to Siwa. On 3 February the armoured cars surprised and engaged the Senussi at Girba, who retreated overnight. Siwa was entered on 4 February without opposition but a British ambush party at the Munassib Pass was foiled, when the escarpment was found to be too steep for the armoured cars. The light cars managed to descend the escarpment and captured a convoy on 4 February. Next day the Senussi from Girba were intercepted but managed to establish a post the cars were unable to reach and then warned the rest of the Senussi. The British force returned to Matruh on 8 February and Sayyid Ahmed withdrew to Jaghbub. Negotiations between Sayed Idris and the Anglo-Italians which had begun in late January were galvanised by news of the Senussi defeat at Siwa. In the accords of Akramah, Idris accepted the British terms on 12 April and those of Italy on 14 April.
Volta-Bani War, 1915–1917
The Volta-Bani War was an anti-colonial rebellion that took place in parts of French West Africa (now Burkina Faso and Mali) between 1915 and 1917. It was a war between an indigenous African army, a heterogeneous coalition of peoples against the French Army. At its height in 1916, the indigenous forces mustered from 15,000–20,000 men and fought on several fronts. After about a year and several setbacks, the French army defeated the insurgents and jailed or executed their leaders but resistance continued until 1917.
Darfur Expedition, 1916
On 1 March 1916 hostilities began between the Sudanese government and the Sultanate of Darfur. The Anglo-Egyptian Darfur Expedition was conducted to forestall an imagined invasion of Anglo-Egyptian Sudan and the Sultanate of Egypt by the Darfurian leader, Sultan Ali Dinar, which was believed to have been synchronised with a Senussi advance into Egypt from the west. The Sirdar (commander) of the Egyptian Army organised a force of c. 2,000 men at Rahad, a railhead 200 mi (320 km) east of the Darfur frontier. On 16 March, the force crossed the frontier mounted in lorries from a forward base established at Nahud, 90 mi (140 km) from the border, with the support of four aircraft. By May the force was close to the Darfur capital of El Fasher. At the Affair of Beringia on 22 May, the Fur Army was defeated and the Anglo-Egyptian force captured the capital the next day. Dinar and 2,000 followers had left before their arrival and as they moved south, were bombed from the air.
