Battle of Stalingrad on Soviet records, over 10,000 German soldiers continued to resist in isolated groups within the city for the next month. Some have presumed that they were motivated by a belief that fighting on was better than a slow death in Soviet captivity. Brown University historian Omer Bartov claims they were motivated by National Socialism. He studied 11,237 letters sent by soldiers inside of Stalingrad between 20 December 1942 and 16 January 1943 to their families in Germany. Almost every letter expressed belief in Germany's ultimate victory and their willingness to fight and die at Stalingrad to achieve that victory. Bartov
Which? centres during the 1970s. More than 120 such centres were operating in 1977-8, many of them funded by local councils. The centres closed as funding was withdrawn by the government in 1980. "Which?" continued campaigning on consumer safety issues, with its car safety test results strengthening calls to legislate car manufacturers to fit seat belts in all new cars, helping to make it compulsory to Clunk Click Every Trip in 1983. In 1992, "Which?" launched another satellite publication, this one aimed at youngsters aged 11–15, called Check It Out!, but it failed to take off and closed in June 1994.
