LIDZBARK WARMINSKI, Poland (AP) — Nearly a century after they died in Germany captivity during World War I, relatives and officials honored 39 British servicemen in a solemn ceremony Friday at their burial site in Poland.

The servicemen died in late 1918, toward the end of the war, from disease and ill treatment at the East Prussian prisoner camp in Heilsberg. Aged between 19 and 37, they were buried in a common grave in the town, which is now part of Poland and called Lidzbark Warminski.
