World War the City Ground held a variety of events to entertain off-duty servicemen, including boxing, horse gymkhanas, and visits from zoos. The pitch was badly damaged by bombing on the night of 8–9 May 1941, with repairs costing £75 9s 11d. Post war The City Ground was flooded after the adjacent River Trent burst its banks in March 1947, with Forest having to play some home fixtures at Meadow Lane. Many archives and official records were damaged and floodwaters reached as high as the crossbars of the goals, with swans seen swimming the full length of the pitch. After winning promotion in 1950 Forest drew up plans for redeveloping the City Ground, and detailed plans were drawn up by local architects Reginald Cooper and Partners in 1951. The first step was the extension and covering of the Trent End in 1954, though a planned second tier of seats at this end was never built. On 12 October 1957, a new East Stand opened, costing £40,000 and having benches to seat up to 2,500 fans to the rear of the terrace. Together with improvements to the Colwick Road Terrace this gave the ground an increased capacity of 48,000, with 6,500 seats for the club's first season in the First Division since 1925. The visitors for the opening were Manchester United's "Busby Babes", just four months before eight of them died in the Munich air disaster, and the match on 12 October 1957 saw a new record attendance of 47,804. Although Forest had pioneered floodlit football matches, holding a game illuminated by Wells lights at the Gregory Ground in March 1889, the City Ground was the second from last top division ground to install permanent floodlights. The floodlights at the ground were first used on 11 September 1961 as Forest faced Gillingham in the League Cup. Four 120 ft pylons were built, one in each corner of the ground, with each pylon holding a bank of thirty-six 1,500 watt lights. The ground's all-time record attendance of 49,946 was set in October 1967 when Forest beat Manchester United 3–1 in a First Division fixture, five months after Forest had finished second to United in the league. In December 1967 the City Ground was host to an England U23 match against Italy. The Main Stand was re-roofed, extended and refurbished between 1962 and 1965, with new offices, changing rooms, kit stores, medical suites
