DANBURY - The young U.S. Army grenadier was alone and crawling through enemy lines toward a German tank. It was January 1945, a major turning point in World War II. The grenadier, Danbury-born Paul Halas Sr., and his comrades in the 90th Infantry Division were locked in the infamous Battle of the Bulge in the Ardennes on the German-Belgium border. Halas, 19, had specific orders. Disable the tank so that his unit could advance. He crawled the 100 yards that separated the two sides and crippled the giant Tiger tank by smashing its track with a rifle grenade. Halas then shot the tank crew when the three men scrambled out of the damaged vehicle, as well as three more Germans who suddenly appeared behind him. "My father always wondered why the Germans didn't shoot him first," Halas' son, Mike Halas , recalled Tuesday. "All he said later was, 'It was my lucky day.' " Paul Halas' action, which earned him a Bronze Star, along with the rest of his service in World War II will be remembered Saturday when family and friends plan to dedicate a flagpole and plaque in his memory outside the family home on Pembroke Road. Paul Halas died last year at the age of 79. "We see the memorial as something that will always be a reminder of my father's sacrifice for his country, as well as the sacrifice made by others like him," said Mike Halas. The ceremony, which starts at 2 p.m. at the Halas Farm Market and Garden Center on Route 37, will be performed by Korean War veterans. It is open to the public and the Halas family will serve refreshments. Paul Halas, who was born and raised in Danbury, was not the only boy in his family to see action in World War II. His brother Ludwig, then 23, served with the U.S. Marine Corps in the Pacific and died at the Battle of Iwo Jima in 1945. His brother John, then 27, who survived, served with the U.S. Army in the Philippines. Paul Halas, whose family ran a 140-acre dairy farm on Bear Mountain Road, enlisted in the Army not long after graduating from Danbury High School in 1943. By December 1944 he was in Europe. The Battle of the Bulge, which involved more than 1 million men, was the result of a German plan to reach the sea, trap four Allied armies, and impel a negotiated peace on the western front. The Germans' strategy failed in the face of fierce resistance, but not without heavy losses on both sides. German casualties totaled 100,000, while the Americans lost 81,000 men. Mike Halas still has a pair of German officer's binoculars that his father took from the battlefield after his raid on the tank. Paul Halas, who became a sergeant, returned to the family farm after the war and married in 1949. He and his wife, Mary Gertrude , now 82, raised a family of seven girls and three boys. The family farm market on Pembroke Road was founded by Halas on an 80-acre tract of land in 1969. It is now run by his son Mike. "My father was still active on the farm until he died," Mike Halas said. Inside his 250-year-old home beside the farm market, Mike Halas has built a shadow box to contain his father's service memorabilia. Alongside the Bronze Star are other service ribbons, including a Purple Heart for wounds his father suffered in battle. Mike Halas and his wife, Laura, now have children of their own - a boy, Michael, 7, and two girls, Madison, 5, and Emma, 3. "My boy is now at that inquisitive age when he sometimes asks about what his grandfather did," said Halas. Halas said his father was never one to volunteer information about his war service. "It was a hell of a time for him," said Mike Halas. "He wouldn't talk about it much unless I really pressed him. He wouldn't tell me the horror stories. The one thing he did say was that war is hell." Contact Brian Saxton at email@example.com or at (203) 731-3332.
