Question: When did Allied troops land in the area where the Arab Slave Trade operated?

full_context: Document 1: 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 2: 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 3: Black people: Beginning several centuries ago, during the period of the Ottoman Empire, tens of thousands of Black Africans were brought by slave traders to plantations and agricultural areas situated between Antalya and Istanbul in present-day Turkey. Some of their descendants remained in situ, and many migrated to larger cities and towns. Other blacks slaves were transported to Crete, from where they or their descendants later reached the İzmir area through the population exchange between Greece and Turkey in 1923, or indirectly from Ayvalık in pursuit of work.
Document 4: Black people: Some succeeded their fathers as rulers, such as Sultan Ahmad al-Mansur, who ruled Morocco from 1578 to 1608. He was not technically considered as a mixed-race child of a slave; his mother was Fulani and a concubine of his father. Such tolerance for black persons, even when technically "free", was not so common in Morocco. The long association of sub-Saharan peoples as slaves is shown in the term abd (Arabic: عبد‎,) (meaning "slave"); it is still frequently used in the Arabic-speaking world as a term for black people.
Document 5: Black people: Genetic studies have found significant African female-mediated gene flow in Arab communities in the Arabian Peninsula and neighboring countries, with an average of 38% of maternal lineages in Yemen are of direct African descent, 16% in Oman-Qatar, and 10% in Saudi Arabia-United Arab Emirates.
Document 6: Africa: The peoples of North Africa consist of three main indigenous groups: Berbers in the northwest, Egyptians in the northeast, and Nilo-Saharan-speaking peoples in the east. The Arabs who arrived in the 7th century AD introduced the Arabic language and Islam to North Africa. The Semitic Phoenicians (who founded Carthage) and Hyksos, the Indo-Iranian Alans, the Indo- European Greeks, Romans, and Vandals settled in North Africa as well. Significant Berber communities remain within Morocco and Algeria in the 21st century, while, to a lesser extent, Berber speakers are also present in some regions of Tunisia and Libya. The Berber-speaking Tuareg and other often-nomadic peoples are the principal inhabitants of the Saharan interior of North Africa. In Mauritania, there is a small but near-extinct Berber community in the north and Niger–Congo-speaking peoples in the south, though in both regions Arabic and Arab culture predominates. In Sudan, although Arabic and Arab culture predominate, it is mostly inhabited by groups that originally spoke Nilo-Saharan, such as the Nubians, Fur, Masalit and Zaghawa, who, over the centuries, have variously intermixed with migrants from the Arabian peninsula. Small communities of Afro-Asiatic-speaking Beja nomads can also be found in Egypt and Sudan.
Document 7: Sahara: The Byzantine Empire ruled the northern shores of the Sahara from the 5th to the 7th centuries. After the Muslim conquest of Arabia (Arabian peninsula) the Muslim conquest of North Africa began in the mid-7th to early 8th centuries, Islamic influence expanded rapidly on the Sahara. By the end of 641 all of Egypt was in Muslim hands. The trade across the desert intensified. A significant slave trade crossed the desert. It has been estimated that from the 10th to 19th centuries some 6,000 to 7,000 slaves were transported north each year.
Document 8: 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).
Document 9: 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 10: Black people: Numerous communities of dark-skinned peoples are present in North Africa, some dating from prehistoric communities. Others are descendants of the historical Trans-Saharan trade in peoples and/or, and after the Arab invasions of North Africa in the 7th century, descendants of slaves from the Arab Slave Trade in North Africa.
Document 11: 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 12: Military history of the United States during World War II: The war against Germany involved aid to Britain, her allies, and the Soviet Union, with the U.S. supplying munitions until it could ready an invasion force. U.S. forces were first tested to a limited degree in the North African Campaign and then employed more significantly with British Forces in Italy in 1943 -- 45, where U.S. forces, representing about a third of the Allied forces deployed, bogged down after Italy surrendered and the Germans took over. Finally the main invasion of France took place in June 1944, under General Dwight D. Eisenhower. Meanwhile, the U.S. Army Air Forces and the British Royal Air Force engaged in the area bombardment of German cities and systematically targeted German transportation links and synthetic oil plants, as it knocked out what was left of the Luftwaffe post Battle of Britain in 1944. With the Soviets unstoppable in the east, and the Allies unstoppable in the west, Germany was squeezed to death. Berlin fell to the Soviets in May 1945, and with Adolf Hitler dead, the Germans surrendered.
Document 13: 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 14: 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 15: Black people: Historians estimate that between the advent of Islam in 650CE and the abolition of slavery in the Arabian Peninsula in the mid-20th century, 10 to 18 million sub-Saharan Black Africans were enslaved by Arab slave traders and transported to the Arabian Peninsula and neighboring countries. This number far exceeded the number of slaves who were taken to the Americas. Several factors affected the visibility of descendants of this diaspora in 21st-century Arab societies: The traders shipped more female slaves than males, as there was a demand for them to serve as concubines in harems in the Arabian Peninsula and neighboring countries. Male slaves were castrated in order to serve as harem guards. The death toll of Black African slaves from forced labor was high. The mixed-race children of female slaves and Arab owners were assimilated into the Arab owners' families under the patrilineal kinship system. As a result, few distinctive Afro-Arab black communities have survived in the Arabian Peninsula and neighboring countries.
