AFP, THIEPVAL: Britain and France on Friday marked 100 years since their troops fought and died side by side in the Battle of the Somme, one of the defining offensives of World War I.
Britain’s royal family, Prime Minister David Cameron and French President Francois Hollande took part in the official commemoration at the Thiepval Memorial in northern France in remembrance of around one million who were left dead, injured or missing in the 141-day battle. Drenched in military pomp and ceremony, the commemoration comes just a week after Britain voted to leave the EU. Hollande highlighted the friendship that united the countries’ troops during the battle.
“I want to recall that it is the European idea which allowed us to overcome divisions and rivalries between states, and which has brought us peace for the past 70 years,” Hollande said in a statement before the ceremony.
Under grey skies, military bands played to some 10,000 guests at the memorial, after the screening of the 1916 film “The Battle of the Somme” with its devastating images of troops going over the top of trenches to their death.
The day began with the blast of whistles on a former battlefield and in Parliament Square in London at 7:30 am sharp to mark the start of the offensive. The previous night Queen Elizabeth attended a night-long vigil in Westminster Abbey while her grandson Prince William was in France along with his wife Kate and brother Harry for a vigil at Thiepval.
 William paid tribute to a generation lost at the Battle of the Somme—with 20,000 soldiers dying on the first day alone in the deadliest day in British military history.
“We lost the flower of a generation, and in the years to come it sometimes seemed that with them a sense of vital optimism had disappeared forever from British life,” said William.
“It was in many ways the saddest day in the long story of our nation.”
The Battle of the Somme, involving troops from across what was then the British Empire, moved the frontline only a few miles.
“We acknowledge the failures of European governments, including our own, to prevent the catastrophe of world war,” said Prince William. At Friday’s ceremony narrators such as actor Charles Dance—who played Tywin Lannister in Game of Thrones—and actress Joely Richardson read out letters and memories of the war and a choir sang the patriotic song “Keep the Home Fires Burning.”
The attritional battle became a defining event in the war, symbolising the horrors of trench warfare and the futility of the conflict. It was also the first battle in which tanks were used.
