Forces personnel and a JLGB member were among a group of 20 people who visited First World War sites in Ypres.
The trip was organised by We Were There Too, a Lottery-funded digital resource on the contribution of London Jews to the war, both in battle and on the home front.
Rabbi Reuben Livingstone, senior Jewish chaplain to HM Armed Forces, was among the group. He said it was important to remember how Jewish immigrants to Britain volunteered to fight in 1914.
“And most of those fighting when Britain first went to war were volunteers because conscription had not kicked in yet.”
The presence of the JLGB’s Jack Sanders, 19, recognised the wartime service of members of JLB, as it was then known. More than 500 died in action.
Wreaths were laid at JLB graves and the group also visited the burial places of Jews who fought for other nations.
“I know British Jews serving across the world in HM Forces are hugely inspired by the heritage of those who served before us,” observed Major Danny Sharpe of the Royal Army Medical Corps, who chairs the Armed Forces Jewish Network.
