the "materialist nightmare" of contemporary capitalist society and underwent a personal "Spiritual Revolution" to dedicate themselves fully to the nation. Security and violence Preoccupied with security, during the 1970s the Front created a file of its opponents' names and addresses. To guard its marches, it formed "defence groups"—later called the "Honour Guard"—who often carried makeshift weapons. These marches often took place in areas with high migrant populations to instil fear in the latter, whip up racial tensions and generate publicity. These tactics have continued into more recent times. Local authorities sometimes banned its marches; in 2012, Aberdeen City Council rejected the NF's request to hold a procession on Adolf Hitler's birthday. The NF also disrupted anti-fascist and mainstream political meetings. In 1975, NF activists attacked a National Council of Civil Liberties meeting, with eight people requiring hospitalisation; in another instance they stormed a Liberal Party meeting discussing the transition to black-majority rule in Rhodesia, chanting "White Power". The Front claimed that its members only resorted to violence in self-defence, although in the 1970s Fielding observed the group using force "aggressively". Fielding believed the most notable violent clash involving the NF was the Red Lion Square disorders in June 1974, during which an anti-fascist protester, Kevin Gateley, was killed. Another prominent clash took place in Lewisham in August 1977, when Trotskyist groups attacked the NF marchers, resulting in the "Battle of Lewisham". In April 1979, an anti-NF demonstration in Southall clashed with police, resulting in the death of Blair Peach. There have also been actions where covert NF involvement was suspected but not proven. For instance, in 1974, several men put up NF posters in Brighton, assaulted individuals they accused of being Jewish and attacked the Communist Party of Britain (Marxist–Leninist) bookshop. The local NF branch denied involvement. In June 1978, the Anti-Nazi League headquarters was hit by an arson attack; the slogan "NF Rules OK" was graffitied on the building. The NF denied responsibility. The party's leadership showed little concern with the violence of its members and supporters, and openly praised some of its members convicted for violent activity. Sub-groups and propaganda output The NF formed various sub-groups. In 1974, it launched the NF Trade Unionists Association, and issued a short-lived trade unionist magazine, The British Worker. During the 1970s it encouraged members to infiltrate other groups, such as the Hunt Saboteurs Association and ratepayers' and residents' associations, through which
