The Affair of Khra [Chra] ("affair" a military engagement by a force less than a division) was fought by British and French troops against German Polizeitruppen(paramilitary police) in the village of Khra, near the Khra River on 22 August 1914, during the Togoland Campaign of the First World War. The German defenders mined the approaches to the river, blew the bridges and dug in around the village on the far bank, ready to defend the crossing with rifles and three concealed machine-guns. The British–French attack was repulsed and then a German counter-attack was ordered but many troops refused the order and the attack was not delivered.
The Germans retired overnight to Kamina, due to apprehension that other British and French troops would cut off the German retreat and overestimation of the number of their opponents. The invaders paused for two days and resumed the advance on Kamina; they were met at Glei, on 25 August, by two Germans who offered terms of surrender. The British commander demanded unconditional surrender and the Germans accepted his terms the next day, ending hostilities. The colony was administered jointly for the duration of the war by the French and British. After the war Togoland was partitioned, the western part of Togoland, administered by the British, joined Ghana in 1957 and French Togoland became independent as Togo in 1960.
Background
Strategic developments
An Offensive Sub-Committee of the Committee of Imperial Defence which had been appointed on 5 August established a principle that command of the seas was to be ensured. Objectives were to be considered if they could be attained by 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 German commerce raiders.
Objectives at Tsingtau in the Far East and Luderitz Bay (Angra Pequena), Windhoek, Duala and Dar es Salaam in Africa, were considered feasible and a German wireless station in Togoland, next to the British colony of Gold Coast (now Ghana) in the Gulf of Guinea, was judged to be within the capacity of local forces. The high-power wireless transmitter had been built at Kamina and controlled German wireless communication in the Atlantic Ocean, by linking a German transmitter at Nauen near Berlin with German colonies in west Africa and South America.
At the outbreak of war, the German acting-Governor of Togoland, Major Hans Georg von Doering, who had 152 paramilitary police, 416 local police and 125 border guards but no regular army forces, had proposed neutrality to the British and French colonial authorities, under the Congo Act 1885. The Germans had withdrawn from Lomé and the coastal region, when the British demanded unconditional surrender.
Doering, in the absence of the Governor Duke Adolf Friedrich of Mecklenburg, had sent an un-coded wireless message to Berlin disclosing his plan to retreat to Kamina, which had been intercepted and led to British offensive operations against Kamina being authorised by the Colonial Office on 9 August. Expeditions from northern Dahomey, Nigeria and the Gold Coast began on 12 August.
Tactical developments
British forces, under the command of Lieutenant-Colonel F. C. Bryant, from the Gold Coast, a colony to the west of Togoland and French forces from the colony of French Dahomey to the east, invaded Togoland. Late on 6 August, French police occupied customs posts near Athiémè and the village of Agbanake was occupied late on 7 August. The Mono River was crossed and Aného was captured early on 8 August. About 460 German colonists and Askaris retreated inland, impressing civilians and calling up reservists as they moved north. The French advanced to Porto Seguro and Togo, before stopping the advance when Lomé, the Togoland capital, was surrendered to British forces. The British had sent two officers to Lomé on 6 August with a demand to surrender the colony within 24 hours and invaded Togoland late on 7 August. The Germans left for Kamina and surrendered Togoland up to the Khra River, 75 mi (120 km) inland, to prevent a naval bombardment of Lomé.
By 12 August, the Togo coast and Lomé had been occupied, with little resistance from the Germans who had withdrawn to Kamina, 100 mi (160 km) inland, on hills near Atakpamé. A wireless station had been built at the village for communication between Germany and its African colonies, South America and German shipping in the Atlantic. The only routes inland were by the railway and road, which had been built through dense and almost impassable jungle. The Anglo-French advance towards Kamina was slowed by German demolitions of railway bridges, which made movement difficult and delayed the transport of supplies. Captain Georg Pfähler, the German military commander, travelled south on two trains with 200 soldiers, towards the main Entente columns. The Germans were ambushed and defeated at the Affair of Agbeluvoe on 15 August and Pfähler was killed. The Germans had many casualties and fled, leaving 30 mi (48 km) of railway to the north intact. On 17 August, the British force was joined by 150 French Tirailleurs Sénégalais under Captaine Castaing.
Prelude
Peripheral operations
On 4 and 5 August, in the north of the Gold Coast colony, two twenty-man detachments of Northern Territories Constabulary, advanced from Tamale to Zan on the frontier. Due to a misunderstanding, orders from Bryant for a company of the Gold Coast Regiment already in Zan, to occupy Krachi had also been obeyed by the Constabulary. Tamale was left undefended and was feared vulnerable to attack by about 250 German troops, who were known to have left Sansane Mangu, heading south. The Chief Commissioner of the Northern Territories had also heard that the German Commissioner was still at Yende. Orders were dispatched to the Constabulary to return to Zan and the Commandant of the Constabulary, Major J. Marlowe, was ordered to take all the trained men left at Tamale and advance on Yende, if agent reports were favourable. Marlowe advanced on 12 August and occupied Yende unopposed on 14 August, where it was found that the Germans had learned through their agents, that the Constabulary had left Tamale, had assumed that their arrival at Yende was imminent and left the next day.
More small detachments of the Constabulary, amounting to 139 men, invaded northern Togoland at various points. Further south 48 men of the Gold Coast Service occupied Ho unopposed on 17 August. Bryant ordered the detachments at Lomé and Ho to move to Palime to guard the flank of the main force, advancing from the south. Two Preventive Service officers used a motor cycle to drive about 30 mi (48 km) from Lomé and cut the Lomé–Palime railway line. The Germans in Palime retired soon afterwards and blew up the road and rail bridges at Agu. By 18 August, the railway bridge at Togblekove had been repaired. In the north of Togoland, British and French troops, police and volunteers invaded and reached Yendi and Sansane Mangu by 14 August.
A small French force invaded Togoland from north-west French Dahomey on 9 August and four days later met and skirmished with the German defenders in the districts of Sansane-Mangu and Skode-Balfilo; the French company retreated after finding German resistance greater than expected. More detachments followed, c. 200 Togolese troops in the area deserted, many of the rest retreated and the local civilian authorities hurried to repudiate German allegiance. M. Duranthon advanced from Fada Ngurma with about 140 police and volunteers, was followed by M. Arboussier with a force of c. 120 volunteers and police from Ouagadougou and Captitaine Bouchez with about 130 soldiers of the 2nd Tirailleurs Sénégalais. Arbroussier reached Sansane Mangu on 23 August and Bouchez on 26 August, having covered 372 mi (599 km) in twenty days. A British column of 104 men from Gambaga arrived at Sansane Mangu on 18 August and c. 400 French police and volunteers occupied other places in northern Togoland, having crossed difficult country, little known to the colonial occupiers.
Entente preparations
Bryant began the main advance on 19 August and notified Major Maroix, the commander of a French force at Cheti and Captain P. E. L. Elgee, in command of the Krachi column, that he expected to reach the river Amuchu on 26 August. Bryant desired them to be within two days' march of Kamina by then. Bryant sent the messages by runner, in the belief that local civilians were hostile to the German colonialists, who had on occasion, coerced civilians with death threats, to oppose the British and French. Local civilians had been willing to assist the British and French as soon as they invaded the colony. Maroix had 368 French and Sénégalais troops and reservists, supported by a section of artillery. Having concentrated at Cheti on 19 August, the French began to advance on Kamina on 22 August. The Krachi Column, with A, B and F companies of the Gold Coast Regiment, had arrived from 16 to 18 August, using canoes to cross the Volta. The column departed Kete Krachi along the Kpandu road on 19 August.
The Affair of Agbeluvoe was considered a great defeat of the Germans by local civilians but it delayed briefly the British advance to the north, until 19 August. The German force of one German and seven local companies of c. 1,500 men had been expected to be most formidable, given the Togolese terrain. The Germans were not able to obtain information about the British in the neighbouring colony of Gold Coast (now Ghana) and instructions by wireless from Berlin, merely insisted that the transmitting station be protected. In the first three weeks of August, the transmitter at Kamina had passed 229 messages from Nauen in Germany to German colonies and German shipping. Scouts under Captain A. F. Redfern arrived near the southern bank of the Khra River on 21 August. The Germans blew the bridge and detonated two mines in the path of the scouts, who were then engaged by fire from two machine-guns. The patrol was able to survey the German defences and retire unharmed to report the German entrenchments around the village, 500 yd (460 m) north of the bridge, to Bryant.
Entente plan
Dense bush made an attack difficult, because observation beyond a few yards was impossible, making it difficult to maintain direction, provide mutual support or to gain a sufficient field of fire for supporting machine-guns, which would also be limited by the difficulty of transporting ammunition. Bryant decided on an attack from two directions, preceded by a screen of skirmishers. On the right near the railway, the Pioneer and part of G Company of the Gold Coast Regiment and Castaing's French detachment were to advance around the left flank, while the Pioneer Company was to pin down the Germans frontally. Half of C Company, I Company and three guns of the Gold Coast Regiment were to advance around the right flank, while half of C Company pinned down the Germans opposite, the guns giving such support as they could. The half of G Company attacking near the railway was reinforced by seventeen of the French Sénégalais soldiers for the attack.
German preparations
The road and railway ran north through Khra, which the Germans chose as the point to make a stand in defence of Kamina further north. Khra lay west of the railway, on either side of the road and was about 150 yd (140 m) wide and 400 yd (370 m) long. The railway from Khra to Kamina remained open to carry supplies and reinforcements to the German force of c. 440 troops, which had three days to dig in, before Allied forces arrived from the south on 21 August. Entrenchments were dug around the fringe of the village and eastwards to a nearby railway cutting; three or four machine-guns were dug in on the flanks, to command all approaches of attack and the road and railway bridges, which were about 500 yd (460 m) south of Khra were mined.
Engagement
G Company and the party of Tirailleurs Sénégalais worked through the bush on the German left flank until about 11:00 a.m., when they were stopped by rifle and machine-gun fire from entrenched German troops. Both sides exchanged fire until 3:30 p.m., when Lieutenant G. M. Thompson considered that a superiority of fire had been achieved and ordered the attack. German small-arms fire increased and the attack was stopped 50 yd (46 m) from the German entrenchments, Thompson, Maroix and many of the soldiers having been killed or wounded; the survivors retired. On the left flank, I Company made its way around the German right flank against much small-arms fire but found more trenches and lacked the number of men necessary to risk an attack. When dark fell, the party withdrew and dug in along the riverbed about 300 yd (270 m) west of the village. Two of the British guns had been brought into action from a range of 1,300 yd (1,200 m) but lack of view made the result impossible to know.
