to Scotland. Later, the last 150 men were also evacuated. With Longyearbyen depopulated, a small German garrison and air strip were established in Adventdalen, mostly to provide meteorological data. After the British Operation Fritham regained control of Barentsburg, the German forces left Longyearbyen without combat. In September 1943, the Kriegsmarine dispatched two battleships, Tirpitz and Scharnhorst, and nine destroyers to bombard Longyearbyen, Barentsburg and Grumant. Only four buildings in Longyearbyen survived: the hospital, the power station, an office building, and a residential building. Longyearbyen remained unsettled until the end of the war, with the first ship from the mainland leaving on 27 June 1945. Post-Second World War Plans were laid during the war to ensure a quick reconstruction and restarting of mining. By 1948, coal production had reached the pre-war level of per year. Nybyen was established in 1946 and consisted of five barracks, each housing 72 people. The first issue of Svalbardposten was published in November 1948. Until then, various wall newspapers had been published irregularly. In 1949, Longyearbyen received a telephone connection with the mainland via a radio connection between Svalbard Radio and Harstad. In 1949, a farm was built in Longyearbyen to hold cattle (for milk), pigs, and hens. A local radio station started broadcasting in 1950. The burial ground remained in use until 1950, with 44 people buried. However, it was discovered that the bodies were failing to decompose because of the permafrost, and that they could be preserving various microorganisms. Bodies have since been sent to the mainland for burial. The community centre Huset opened in 1951. Mining in Mine 1b was terminated in 1958, but operation in Mine 5 started the following year. Preliminary work on Mine 4 started in 1954, and from 1960 it was used as a reserve mine. The Norwegian Air Force started serving Longyearbyen with postal flights in the 1950s. In 1959, a man fell seriously ill, so a landing strip was prepared in Adventdalen. From the same year, Braathens SAFE started serving the tundra airport with irregular winter flights. In 1957, a principal was hired at the primary school and a new church was opened on 24 August 1958. From 1961, the primary school was supplemented by a private middle school. A branch of Tromsø Sparebank opened in 1959. In the 1960s, the town's farm was closed and replaced by industrial liquefaction of powdered milk. The first serial-produced snowmobile
