Jean-Pierre Calloc'h

Yann-Ber Kallocʼh was a Breton war poet who wrote in both Breton and French. Similarly to the English poet Wilfred Owen and the Welsh poet Hedd Wyn, Kallocʼh was killed in action during trench warfare while serving as a poilu during World War I. Kallocʼh's death was an equally catastrophic loss to Breton literature.
