Kabul River (Persian: دریای کابل‎; Pashto: کابل سیند; Urdu: دریای کابل), the classical Cophes ( /ˈkoʊfiːz/), is a 700 km long river that starts in the Sanglakh Range of the Hindu Kush Mountains in Afghanistan and ends in the Indus River near Attock, Pakistan. It is the main river in eastern Afghanistan and is separated from the watershed of the Helmand by the Unai Pass. It passes through the cities of Kabul, Chaharbagh and Jalalabad in Afghanistan before flowing into Pakistan some 25 km north of the Pak-Afghan Border crossing at Torkham. The major tributaries of the Kabul River are the Logar, Panjshir, Kunar, Alingar, Bara and Swat rivers.

The Kabul River is little more than a trickle for most of the year, but swells in summer due to melting snows in the Hindu Kush Range. Its largest tributary is the Kunar River, which starts out as the Mastuj River, flowing from the Chiantar glacier in Chitral, Pakistan and after flowing south into Afghanistan it is met by the Bashgal river flowing from Nurestan. The Kunar meets the Kabul near Jalalabad. In spite of the Kunar carrying more water than the Kabul, the river continues as the Kabul River after this confluence, mainly for the political and historical significance of the name.

Kabul ( /ˈkɑːbəl/, /ˈkɑːbuːl/; Pashto: کابل Kābəl, IPA: [kɑˈbəl]; Persian: کابل Kābol‎, IPA: [kɒːˈbol]), also spelled Cabool, Caubul or Cabul, mostly in historical contexts, is the capital and largest city of Afghanistan. Kabul is the 5th fastest growing city in the world [2] and the world's 64th largest city [3]. It is also the capital of Kabul Province, located in the eastern section of Afghanistan. According to latest estimates, the population of the Kabul metropolitan area is over 4 million.

The city serves as the nation's cultural and learning centre, situated 1,791 metres (5,876 ft) above sea level in a narrow valley, wedged between the Hindu Kush mountains along the Kabul River. It is linked with Kandahar, Herat and Mazar-e Sharif via the circular Highway 1 that stretches across Afghanistan. It is also the start of the main road to Jalalabad and further to Peshawar, Pakistan. The Kabul International Airport is located about 16 kilometres (9.9 mi) from the center of the city, next to the Wazir Akbar Khan neighborhood. Bagram Airfield is about 40 kilometres (25 mi) northeast of Kabul.

Joseph Rudyard Kipling ( /ˈrʌdjəd ˈkɪplɪŋ/ RUD-yəd KIP-ling; 30 December 1865 – 18 January 1936) was an English poet, short-story writer, and novelist chiefly remembered for his tales and poems of British soldiers in India, and his tales for children. Kipling received the 1907 Nobel Prize for Literature. He was born in Bombay, in the Bombay Presidency of British India, and was taken by his family to England when he was five years old. Kipling is best known for his works of fiction, including The Jungle Book (a collection of stories which includes "Rikki-Tikki-Tavi"), Just So Stories (1902) (1894), Kim (1901) (a tale of adventure), many short stories, including "The Man Who Would Be King" (1888); and his poems, including Mandalay (1890), Gunga Din (1890), The White Man's Burden (1899) and If— (1910). He is regarded as a major "innovator in the art of the short story"; his children's books are enduring classics of children's literature; and his best works are said to exhibit "a versatile and luminous narrative gift".
