On Friday 24th April 1812, Betty Armstrong was at the door of an Inn in Huddersfield when she was set by a group of people. Nearby were a group of cavalry soldiers, and one of them managed to get her away from the crowd before she was too seriously hurt. She was suspected of having given information about people held on suspicion of being Luddites by the authorities.
At midday on Saturday 25th, she was on her to way to see Joseph Radcliffe when she again set upon and badly beaten by a group of people. In the fracas, she had suffered a fractured skull.
