1913 also saw a continuation of more hard-line methods, with the WPSU firebombing a house which was being built for Lloyd George.[49][50] Between April and September 1913, hoax bombs were set at both Cardiff and Abergavenny, and at Llantarnam, telegraph wires were cut.[48] This period also saw the actions of one of Wales' most notable suffragettes, Margaret Haig Mackworth, daughter of MP D. A. Thomas and his activist wife Sybil Thomas. Mackworth had been recruited into the WPSU in 1908 and had been a vocal and active member from that date, later founding the Newport branch of the organisation.[29][51] In 1913 she was convicted of setting fire to a post box and after refusing to pay the fine was sent to prison at Usk.[48][51] While imprisoned Mackworth went on hunger strike, but was released under the 'Cat and Mouse Act'.[52]
