The first military action taken by modern day Welsh nationalists - and by this I mean those who didn't actually want to get caught - was the bomb attack on the Fron aqueduct, near Crossgates, on October 19th 1952.
I've always been aware of that event since it was covered in national newspapers which also happened to carry a photograph of your blogger, merrily waving a Union Jack outside Llandrindod railway station. The occasion was the visit of the Queen to open the Claerwen reservoir and my excuse for such an uncharacteristic display of British enthusiasm?.... I was just three years old.
Given the early connection between Radnorshire and the subsequent 1960s militancy, which is the subject of this new book from Gwasg Gomer, it's somehow fitting that the author was born and brought up in Llandrindod.
I'm off to read it now.
