From the Dept of Defense MOH Monday Website (Jan 4, 2021):
Thousands of American soldiers who volunteered to fight the Nazis had plenty of reasons to partake in one of the most perilous missions ever fought. But perhaps few had more than Army Staff Sgt. Isadore Jachman — one of three Jewish men to receive the Medal of Honor for actions during World War II.
Jachman was born on Dec. 14, 1922, in Berlin. His parents immigrated to Baltimore when he was 2 and expanded their family further, having another boy and a girl.
A man in a military uniform smiles for the camera. Jachman graduated from Baltimore City College High School in 1939. According to a September 1950 article in the Texas Jewish Post, he spent a year studying physical education at the University of Baltimore before the United States' entrance into World War II changed the trajectory of his life.
In November 1942, he paused his studies and volunteered for the Army.
As a German Jew, Jachman still had plenty of family in Europe, so there was no question where his loyalties lay — with his adopted home, not with the Nazi party that had taken over his native country. According to U.S. Citizenship and Immigration Services, at least six of Jachman's aunts and uncles were killed during the Holocaust.
After basic training, Jachman was posted stateside, but he eventually volunteered to serve as a paratrooper so he could fight the Nazis. After the appropriate training, he was sent to Europe to fight with the 513th Parachute Infantry Regiment of the 17th Airborne Division.
Jachman's unit was part of the massive force fighting back the Nazis during the Battle of the Bulge over the frigid winter of 1944-1945. If it hadn't been for his bravery toward the end of that long and bloody battle, his company might have been completely wiped out.
Soldiers march near a vehicle along a winding road in a snow-covered forest. On Jan. 4, 1945, Jachman was with Company B in Flamierge, Belgium, when they were suddenly pinned down by heavy fire, including artillery, mortar and a barrage of fire from two enemy tanks that quickly inflicted casualties on his unit.
Jachman saw his comrades were in desperate need of something that would help them. Instead of staying where he had taken cover, he jumped up and ran across open ground, despite the gunfire. He grabbed a bazooka from a fallen soldier and moved toward the tanks, which had begun concentrating their fire on him.
Jachman managed to fire the bazooka, damaging one of the armored vehicles before both tanks turned away from the fight. His bold move disrupted the enemy's attack, which saved Company B from complete decimation.
Unfortunately, Jachman was fatally wounded during the attack. He was 22 years old.
Posthumous Honors:
According to the Texas Jewish Post, Jachman was initially awarded the Distinguished Service Cross, which was later upgraded to the Medal of Honor. In June 1950, it was presented to his parents by Army Lt. Gen. Leonard Gerow, the commander of the 2nd Army, during a ceremony at Fort Meade, Maryland.
MILITARY HALL OF HONOR:
Isadore Seigfreid 'Izzy' Jachman ; Staff Sergeant, U.S. Army; Medal of Honor Recipient; World War II;
Staff Sergeant Isadore Seigfreid 'Izzy' Jachman (14 December 1922 - 4 January 1945) was a U.S. Army soldier who was posthumously awarded the U. S. military's highest award for valor, the Medal of Honor, for his heroic actions during World War II.
Isadore Seigfreid Jachman was born on 14 December 1922 in Berlin, Germany, the first son of Leo and Lotte Jachmann. The family moved to the U.S. when Isadore was two years old and Leo 'Americanized' his last name by dropping the second 'n.' Leo and Lotte had two more children, Joe and Sylvia, both "Yankees" born in the U.S. Izzy was raised in Baltimore, MD, and attended high school at the Baltimore City College, graduating in 1939. Jachman, who was Jewish, had relatives who died in the Holocaust, including six aunts and uncles. He joined the U.S. Army in Baltimore after the attack on Pearl Harbor.
The Mission:
At Flamierge, Belgium, on 4 January 1945, Sergeant Jachman, Company B, 513th Parachute Infantry Regiment and his company were pinned down by enemy artillery, mortar, small arms fire and two hostile tanks that attacked the unit, inflicting heavy casualties. Sergeant Jachman left his place of cover, dashed across open ground, through a hail of fire and grabbed a bazooka from a fallen comrade. He then advanced on the tanks, which concentrated their fire on him. Firing his weapon, he damaged one and forced both of them to retire. He suffered fatal wounds during his heroic actions and was posthumously awarded the Medal of Honor. 'Izzy' Jachman had made the supreme sacrifice for his adopted country.
