Mae Trydedd Frwydr Ypres o arwyddocâd arbennig i Gymru am i lawer iawn o filwyr o Gymru golli eu bywydau yno, gan gynnwys y bardd Hedd Wyn. Lladdwyd Hedd Wyn ar 31 Gorffennaf 2017 a chafodd ei gladdu ym mynwent Artillery Wood ger Ypres.
The Third Battle of Ypres is of particular resonance for Wales as it claimed the lives of many Welsh soldiers including the renowned Welsh language poet, Hedd Wyn. Hedd Wyn was killed on 31 July 1917 and is buried at the nearby Artillery Wood cemetery, close to Ypres.
