 In the joint autobiography written with Jack , The Braddocks ( 1963 ) , Bessie cites the formative experience of police violence on " Bloody Sunday " in 1911 as a motivating factor for her CPGB activities . On 12 September 1921 , again at St George 's Plateau , she attended a rally for the city 's jobless , organised by the Liverpool Unemployed Workers ' Committee . Again there was police intervention ; Jack and Mary Bamber were charged with unlawful assembly and received a token one day 's imprisonment . In 1922 Bessie and other party members provided comfort and shelter to Hannington 's hunger marchers , as the columns of unemployed passed through Lancashire on their way to London . Bessie combined her party roles — she was treasurer of the Liverpool branch — with her full @-@ time union post ; Jack , meanwhile , was only intermittently in work , as his incendiary reputation meant that employers were reluctant to give him a job . He had been living for some time at the Bambers ' home when , in February 1922 , the couple were married at Brougham Terrace registry office , during the course of a working day . After a brief reception they returned to their respective duties — Bessie to her union job and Jack to his volunteer work for the CPGB .
