Rows of crosses mark the graves of American soldiers at the Meuse-Argonne American cemetery in Romagne-sous-Montfaucon. The World War I battle was America's largest and deadliest ever, with 26,000 U.S. soldiers killed and tens of thousands wounded. A hundred years ago, the Meuse-Argonne offensive helped bring an end to WW I.

PARIS — It was America's deadliest battle ever, with 26,000 U.S. soldiers killed, tens of thousands wounded and more ammunition fired than in the whole of the Civil War. The Meuse-Argonne offensive of 1918 was also a great American victory that helped bring an end to World War 1.

Officials, descendants of soldiers and visitors have braved strong winds and rain to attend a remembrance ceremony on Sunday afternoon in the Meuse-Argonne cemetery, which is surrounded by green fields and forests in Romagne-sous-Montfaucon, a village in northeastern France.

Organizers had planned to light 14,000 candles to honor those buried there before nightfall, but it was feared the event might be disrupted by rain.

Early Sunday, volunteers began reading the soldiers' names aloud, while others were in charge of placing candles on all the crosses. Covering 130 acres, Meuse-Argonne is the largest American cemetery in Europe.

William Matz, secretary of the American Battle Monuments Commission (ABMC) that maintains the site, told The Associated Press that this piece of history must be retold to younger generations.

“I think it's important for their teachers, their parents to bring them to these beautiful sites, let them walk through the rows of crosses, let them look at the walls of remembrance, let them go into the cemetery chapels and let them learn the history of what these men did 100 years ago,” he said.

“It's because of their brave deeds, their acts of valor and courage and commitment ... that these young folks are able to live and enjoy the life that they're living,” he added.

During seven weeks of combat, 1.2 million American troops led by Gen. John J. Pershing fought to advance on the entrenched positions held by about 450,000 Germans in the Verdun region.The offensive that started on Sept. 26, 1918, was one of several simultaneous Allied attacks that brought the war which started in 1914 to an end, leading the Germans to retreat and sign the armistice on Nov. 11.Pershing said “the success stands out as one of the very great achievements in the history of American arms.”At the cemetery, eight wide grave sections with long regular rows of crosses stretch between the trees on the gentle slopes of a hill. On top is a chapel where the names of 954 missing American soldiers, whose bodies were never found or identified, are engraved.
