 The war inspired Hedd Wyn's work and produced some of his most noted poetry, including "Plant Trawsfynydd" ("Children of Trawsfynydd"), "Y Blotyn Du" ("The Black Dot"), and "Nid â’n Ango" ("[It] Will Not Be Forgotten").His poem, "Rhyfel" ("War"), remains one of his most frequently quoted works.Although farm work was classed as a reserved occupation due its national importance, in 1916 the Evans family were required to send one of their sons to join the British Army.
