German East Africa, acquired by Germany during the 1880s, covered roughly , and by 1914 was home to about 5,000 white settlers, most of whom were of German origin. Because of the British
Royal Navy's domination of the
Indian Ocean, German East Africa was largely isolated from outside help. It therefore fought a war of improvisation, judicious resource management and unorthodox strategy. During the conflict, its military strength grew to a peak of 3,300 whites and anywhere between 15,000 and 30,000
askaris, all commanded by
Generalmajor Paul von Lettow-Vorbeck.
2nd Rhodesia Regiment Based around the overflow of volunteers for the 1st Rhodesia Regiment, a core of personnel for a second Southern Rhodesian expeditionary unit was in place by November 1914. This was made into the 2nd Rhodesia Regiment (2RR) during December 1914 and January 1915. The 1st Rhodesia Regiment's lack of combat experience thus far influenced those men in Southern Rhodesia who were yet to enlist; many Rhodesian colonials were keen to fight on the front lines, and some resolved that they might have to travel to Europe to be sure of doing so. Aware of this competition with the Western Front for the colony's manpower, recruiters for the 2RR took great care to assure potential inductees that they would definitely see combat, in Africa, if they signed up for the new unit. The 2RR ultimately had a paper strength of 500 men, the same as the 1st. Thirty black scouts, recruited in Southern Rhodesia, were also attached to the regiment. Because it was raised with less urgency, the 2RR received better training than the 1st. The course lasted eight weeks, a fortnight longer than the original regiment's training period, and focused heavily on route marching, parade drill, and, in particular, marksmanship—recruits were trained to shoot accurately at ranges of up to . The 2RR left Salisbury on 8 March 1915, moving east to the port of
Beira in
Portuguese Mozambique, from where they sailed to
Mombasa in British
Kenya, on German East Africa's north-eastern flank. Travelling aboard the SS
Umzumbi, the battalion disembarked in Kenya less than a week after leaving Salisbury. It was immediately sent inland to the operational area around
Mount Kilimanjaro, within sight of which it set up camp. On 20 March, the regiment was inspected by General J M Stewart of the
Indian Army. "I had expected to see a regiment that would require some training," Stewart said; "I will pay you the highest compliment by sending you to the front today." So began the 2RR's contribution to the
East African Campaign. Tropical disease killed or rendered ineffective far more 2RR men than the Germans did; at times the regiment was reduced to an effective strength of under 100 by the vast myriad of potential ailments, including
trench fever,
blackwater fever,
dysentery,
pneumonia,
sleeping sickness and many others. The 1,038 personnel who served with 2RR in East Africa collectively went into hospital 2,272 times, and there were 10,626 incidences of illness—in other words, the average 2RR soldier was hospitalized twice and reported sick 10 times. it was no longer an effective fighting force, and the white Southern Rhodesian manpower did not exist to continue reinforcing it. It was therefore withdrawn from East Africa that month. Those men who were healthy enough to return home arrived back in Salisbury on 14 April 1917, receiving a tumultuous welcome, but the majority of 2RR remained in medical care overseas for some time afterwards. The Company briefly considered sending a revived 2RR to the Western Front, but the British Army promptly rejected this idea, saying that the unit would be impractical for trench warfare because of its small size. The battalion was thereupon dissolved, but most of its remaining men went to war in Europe anyway, generally with South African units. This was changed to the more inclusive "
Rhodesia Native Regiment" (RNR) on 15 May 1916, as the ranks proved to be more diverse than expected, and included large numbers of
Mashonas and other ethnicities. The RNR was organized largely along linguistic and cultural lines, with companies and platoons of Matabele, Mashona,
Wayao and others. White officers attached to the unit were often recruited because they knew an African language, or could give orders in
Chilapalapa, a
pidgin of English and several African tongues often referred to by whites of the time as "kitchen kaffir". The ranks' diversity sometimes led to confusion when messages or directives were not properly understood. It became common for black troopers accused of disobeying or ignoring commands to claim ignorance of the language in which they had been ordered. Commanded by Lieutenant-Colonel A J Tomlinson, the RNR, comprising 426
askaris and about 30 white officers, left Salisbury in July 1916 for Beira. They continued on to
Zomba, in Nyasaland, where they were to receive further training closer to the field of operations. When they arrived, the local situation had shifted significantly, so the RNR instead went to New Langenberg, in German East Africa, just north of
Lake Nyasa. At New Langenberg the regiment went through a short training course, and was issued with six machine guns. When the unit's training period ended in October 1916 it was divided; one company of RNR men went to Buhora, about north-east, while the rest went south to Weidhaven, on the north banks of Lake Nyasa, from where they moved east to
Songea, which they were ordered to "hold ... until reinforced". Apart from a company of men sent to patrol the road back to Weidhaven, the RNR proceeded to garrison Songea. The Germans, who had left Songea only a few weeks before, sent two columns to retake it during early November 1916–250
askaris marched from Likuyu, and 180 more (with two machine guns) set off from Kitanda. The latter German column spotted the RNR company that was patrolling the road, and at Mabogoro attacked the advance guard, which was commanded by Sergeant (later Lieutenant)
Frederick Charles Booth. The Rhodesians were caught by surprise, and many panicked, running about and firing randomly. Booth restored discipline and led the defense until reinforcements arrived. The Germans then retreated and continued towards Songea. During this contact, Booth advanced towards enemy fire to rescue a wounded scout who was lying in the open, and brought him back alive; for this and subsequent actions, Booth received the
Victoria Cross in June 1917. In Southern Rhodesia, Company officials judged the RNR to have been a success so far, and so decided in January 1917 to raise a second battalion. The unit already in the field was at this time designated 1st Battalion, abbreviated to "1RNR", while the new formation was called 2nd Battalion, or "2RNR". Nyasalanders eventually made up nearly half of the regiment. By the start of March, about 1,000 recruits were training in Salisbury. Meanwhile, 1RNR was instructed to guard the Igali Pass, near the border with Northern Rhodesia, to prevent a column of Germans from threatening the settlements of
Abercorn and Fife. When the Germans slipped through, the Rhodesians were pulled back to a position between the two towns and instructed to defend either one as circumstances dictated. The Germans did not launch an attack, however, instead setting up camp in their own territory at
Galula. On 5 April 1917, 1RNR crossed the Songwe River into German East Africa and advanced south-east towards Kitanda. It moved up the winding Lupa River, crossing it at each turn, for 53 days, and by mid-June was north of its target. When it was then ordered to backtrack north to
Rungwe, it covered the in 16 days. McLaughlin contrasts the RNR's black troopers with the white soldiers of the 2nd Rhodesia Regiment, commenting that the former proved far more resilient to tropical diseases (though not immune), and amazed white observers by not just adapting to the difficult East African conditions, but often marching in a day. In June 1917, Sergeant Rita (or Lita), a black
non-commissioned officer later described by Tomlinson as "a splendid soldier", received the highest award ever given to an RNR
askari, the
Distinguished Conduct Medal, "for conspicuous gallantry in action on many occasions. His example and influence with his men is incalculable". The 1st Battalion harassed the constantly moving German
flying column during August and September 1917. Two
Military Medals were won by RNR soldiers during this time: Sergeant Northcote rescued a wounded
askari under German fire in late August, and a few days later Corporal Suga, himself lightly injured, dragged his wounded commanding officer Lieutenant Booth out of the open and into cover. After 1RNR spent two months garrisoning Wiedhaven and 2RNR underwent further training, the two forces joined on 28 January 1918 (becoming known as the 2nd Rhodesia Native Regiment), and immediately made their way south in pursuit of Lettow-Vorbeck's Germans, who were by now down to an effective strength of less than 2,000, In the capital, the RNR men were met at the railway station by thousands of people, including a number of prominent government, military and religious figures. Chaplin, the territorial administrator, gave a speech in which he applauded the troops for "upholding the good name of Rhodesia" and for having played "no insignificant part in depriving the Germans of their power in Africa". In Mozambique, the RNR encountered Lettow-Vorbeck's supply column near Mtarika on 22 May 1918. It wiped it out (capturing two German officers, two German
askaris, 34 Portuguese
askaris and 252 carriers), but as the supply column had been marching between the main German column and its rearguard, Lettow-Vorbeck was then able to attack the RNR from both sides. The contact lasted until darkness fell, and the RNR held its position. Lettow-Vorbeck then moved further south, with the RNR following. ==Home front==
