The Front claimed that its members only resorted to violence in self-defence. On observing the group during the 1970s however, Fielding noted that "the NF uses force aggressively", and was "not above exacting revenge" on its critics. Fielding believed the most notable violent clash involving the NF was the Red Lion Square disorders in June 1974. An NF meeting at central London's Conway Hall resulted in clashes between the NF, anti-fascists, and police stationed to keep the peace; 54 demonstrators were arrested, many were injured, and one anti-fascist, Kevin Gateley, was killed. Another prominent clash took place in Lewisham, south-east London in August 1977. The NF marchers were met by a group called the All Lewisham Campaign against Racism and Fascism (ALCARAF), although Trotskyist groups regarded ALCARAF's peaceful response as ineffective and attacked the NF marchers, resulting in the "Battle of Lewisham". In April 1979, an anti-NF demonstration in Southall clashed with police seeking to keep the NF and anti-fascists apart; the violence resulted in the death of Blair Peach.
