Eleni, mae'n gan mlynedd ers Brwydr Passchendaele, un o brif frwydrau'r Rhyfel Byd Cyntaf lle collodd 70,000 o filwyr Prydain eu bywydau. Roedd nifer o'r rheini o Gymru, gan gynnwys y bardd, Hedd Wyn.
This year marks the centenary of the Battle of Passchendaele, one of the key battles of the First World War which cost the lives of 70,000 British soldiers; many from Wales, including the poet Hedd Wyn.
