Question: During WWII when did Allied troops land in the region that Nigeria has traded with for centuries?

full_context: Document 1: Nigeria: For centuries, various peoples in modern-day Nigeria traded overland with traders from North Africa. Cities in the area became regional centres in a broad network of trade routes that spanned western, central and northern Africa. In the 16th century, Spanish and Portuguese explorers were the first Europeans to begin significant, direct trade with peoples of modern-day Nigeria, at the port they named Lagos and in Calabar. Europeans traded goods with peoples at the coast; coastal trade with Europeans also marked the beginnings of the Atlantic slave trade. The port of Calabar on the historical Bight of Biafra (now commonly referred to as the Bight of Bonny) become one of the largest slave trading posts in West Africa in the era of the transatlantic slave trade. Other major slaving ports in Nigeria were located in Badagry, Lagos on the Bight of Benin and on Bonny Island on the Bight of Biafra. The majority of those enslaved and taken to these ports were captured in raids and wars. Usually the captives were taken back to the conquerors' territory as forced labour; after time, they were sometimes acculturated and absorbed into the conquerors' society. A number of slave routes were established throughout Nigeria linking the hinterland areas with the major coastal ports. Some of the more prolific slave traders were linked with the Oyo Empire in the southwest, the Aro Confederacy in the southeast and the Sokoto Caliphate in the north.
Document 2: Dwight D. Eisenhower: In November 1942, he was also appointed Supreme Commander Allied Expeditionary Force of the North African Theater of Operations (NATOUSA) through the new operational Headquarters Allied (Expeditionary) Force Headquarters (A(E)FHQ). The word "expeditionary" was dropped soon after his appointment for security reasons. The campaign in North Africa was designated Operation Torch and was planned underground within the Rock of Gibraltar. Eisenhower was the first non-British person to command Gibraltar in 200 years.
Document 3: Nigeria: In 1885, British claims to a West African sphere of influence received recognition from other European nations at the Berlin Conference. The following year, it chartered the Royal Niger Company under the leadership of Sir George Taubman Goldie. In 1900 the company's territory came under the control of the British government, which moved to consolidate its hold over the area of modern Nigeria. On 1 January 1901, Nigeria became a British protectorate, and part of the British Empire, the foremost world power at the time. In the late 19th and early 20th centuries the independent kingdoms of what would become Nigeria fought a number of conflicts against the British Empire's efforts to expand its territory. By war, the British conquered Benin in 1897, and, in the Anglo-Aro War (1901–1902), defeated other opponents. The restraint or conquest of these states opened up the Niger area to British rule.
Document 4: North African campaign: Fighting in North Africa started with the Italian declaration of war on 10 June 1940. On 14 June, the British Army's 11th Hussars (assisted by elements of the 1st Royal Tank Regiment, 1st RTR) crossed the border from Egypt into Libya and captured the Italian Fort Capuzzo. This was followed by an Italian counter-offensive into Egypt and the capture of Sidi Barrani in September 1940 and again in December 1940 following a British Commonwealth counteroffensive, Operation Compass. During Operation Compass, the Italian 10th Army was destroyed and the German Afrika Korps -- commanded by Erwin Rommel, who later became known as ``The Desert Fox ''-- was dispatched to North Africa in February 1941 during Operation Sonnenblume to reinforce Italian forces in order to prevent a complete Axis defeat.
Document 5: North African campaign: The campaign was fought between the Allies, many of whom had colonial interests in Africa dating from the late 19th century, and the Axis Powers. The Allied war effort was dominated by the British Commonwealth and exiles from German - occupied Europe. The United States officially entered the war in December 1941 and began direct military assistance in North Africa on 11 May 1942.
Document 6: Operation Torch: Operation Torch (initially called Operation Gymnast) was the Anglo - American invasion of French North Africa during the North African Campaign of the Second World War which started on 8 November 1942. It is the first major operation that US troops undertook in the European / North African theatre of World War II.
Document 7: Military history of the United States during World War II: The first stepping stone for the Allied liberation of Europe was, in Prime Minister Winston Churchill's words, the ``soft underbelly ''of Europe on the Italian island of Sicily. Launched on 9 July 1943, Operation Husky was, at the time, the largest amphibious operation ever undertaken. The American seaborne assault by the U.S. 7th Army landed on the southern coast of Sicily between the town of Licata in the west, and Scoglitti in the east and units of the 82nd airborne division parachuted ahead of landings. Despite the elements, the operation was a success and the Allies immediately began exploiting their gains. On 11 August, seeing that the battle was lost, the German and Italian commanders began evacuating their forces from Sicily to Italy. On 17 August, the Allies were in control of the island, U.S. 7th Army lost 8,781 men (2,237 killed or missing, 5,946 wounded, and 598 captured).
Document 8: European exploration of Africa: European exploration of Sub-Saharan Africa begins with the Age of Discovery in the 15th century, pioneered by Portugal under Henry the Navigator. The Cape of Good Hope was first reached by Bartolomeu Dias on 12 March 1488, opening the important sea route to India and the Far East, but European exploration of Africa itself remained very limited during the 16th and 17th centuries. The European powers were content to establish trading posts along the coast while they were actively exploring and colonizing the New World. Exploration of the interior of Africa was thus mostly left to the Arab slave traders, who in tandem with the Muslim conquest of the Sudan established far - reaching networks and supported the economy of a number of Sahelian kingdoms during the 15th to 18th centuries.
Document 9: Central African Republic: During the 16th and 17th centuries slave traders began to raid the region as part of the expansion of the Saharan and Nile River slave routes. Their captives were slaved and shipped to the Mediterranean coast, Europe, Arabia, the Western Hemisphere, or to the slave ports and factories along the West and North Africa or South the Ubanqui and Congo rivers. In the mid 19th century, the Bobangi people became major slave traders and sold their captives to the Americas using the Ubangi river to reach the coast. During the 18th century Bandia-Nzakara peoples established the Bangassou Kingdom along the Ubangi River.
Document 10: Gold Coast (British colony): In 1482, the Portuguese came to the continent for increased trade. They built the Castle of Elmina, the first European settlement on the Gold Coast. From here they acquired slaves and gold in trade for European goods, such as metal knives, beads, mirrors, rum, and guns. News of the successful trading spread quickly, and British, Dutch, Danish, Prussian and Swedish traders arrived as well. The European traders built several forts along the coastline. The Gold Coast had long been a name for the region used by Europeans because of the large gold resources found in the area. The slave trade was the principal exchange and major part of the economy for many years. In this period, European nations began to explore and colonize the Americas. Soon the Portuguese and Spanish began to export African slaves to the Caribbean, and North and South America. The Dutch and British also entered the slave trade, at first supplying markets in the Caribbean and on the Caribbean coast of South America.
Document 11: Operation Collar (commando raid): Operation Collar was the codeword for the first commando raid, conducted by the British forces, during the Second World War. The location selected for the raid was the Pas-de-Calais department on the French coast. The British Commandos had not long been formed and were not yet trained, so the operation was given to No. 11 Independent Company under the command of Major Ronnie Tod.
Document 12: Republic of the Congo: The Portuguese explorer Diogo Cão reached the mouth of the Congo in 1484. Commercial relationships quickly grew between the inland Bantu kingdoms and European merchants who traded various commodities, manufactured goods, and people captured from the hinterlands. After centuries as a major hub for transatlantic trade, direct European colonization of the Congo river delta began in the late 19th century, subsequently eroding the power of the Bantu societies in the region.
Document 13: Atlantic slave trade: The Atlantic slave trade or transatlantic slave trade involved the transportation by slave traders of enslaved African people, mainly from Africa to the Americas, and then their sale there. The slave trade used mainly the triangular trade route and its Middle Passage, and existed from the 16th to the 19th centuries. The vast majority of those who were enslaved and transported in the transatlantic slave trade were Africans from central and western Africa, who had been sold by other West Africans to Western European slave traders (with a small number being captured directly by the slave traders in coastal raids), who brought them to the Americas. The South Atlantic and Caribbean economies especially were dependent on the supply of secure labour for the production of commodity crops, making goods and clothing to sell in Europe. This was crucial to those western European countries which, in the late 17th and 18th centuries, were vying with each other to create overseas empires.
Document 14: Guinea-Bissau: Guinea-Bissau was once part of the kingdom of Gabu, part of the Mali Empire; parts of this kingdom persisted until the 18th century. Other parts of the territory in the current country were considered by the Portuguese as part of their empire. Portuguese Guinea was known as the Slave Coast, as it was a major area for the exportation of African slaves by Europeans to the western hemisphere. Previously slaves had been traded by Arabs north to the northern part of Africa and into the Middle East.
Document 15: North African campaign: The North African Campaign of the Second World War took place in North Africa from 10 June 1940 to 13 May 1943. It included campaigns fought in the Libyan and Egyptian deserts (Western Desert Campaign, also known as the Desert War) and in Morocco and Algeria (Operation Torch), as well as Tunisia (Tunisia Campaign).
