The Rainbow Division Legend is Reborn in World War II
The 42nd Infantry Division was born in 1917 from an act of imagination. Douglas MacArthur proposed drawing National Guard units from 26 states and the District of Columbia into a single division, one that, he famously said, would “stretch across the country like a rainbow”. The name stuck. The Division shipped to France and spent 164 days in combat, third behind only the 1st and 26th Infantry Divisions for time on the line.
They came home a legend … then the world went to war again.
On July 14, 1943, the Rainbow was reactivated at Camp Gruber, Oklahoma, this time composed largely of draftees, but carrying the same name, the same patch, and a tradition that placed something extra on their shoulders before they had fired a single shot. Major General Harry J. Collins took command and told his men plainly: the Rainbow represents the people of our country. This Division cannot fail because America cannot fail.
In November 1944, with the war in Europe at a crisis point, three of the Division's infantry regiments were pulled out of training and rushed to France without their artillery, without their engineering support, without the infrastructure that makes a division whole. Task Force Linden, named for Brigadier General Henning Linden who commanded them, landed at Marseille on December 8, 1944, and moved north toward combat.

The Rainbow Trail
From Alsace to Austria: The Rainbow Division's WWII Combat Path
They arrived in Alsace at Christmas and were in combat before the new year.
Operation Nordwind, Hitler's last major offensive in the West, launched on New Year's Eve 1944, driving German armor and elite infantry into Alsace. Task Force Linden, green soldiers filling the ranks, held a thirty-mile front against forces that had been fighting for years. In the villages of Hatten and Rittershoffen, the 242nd Infantry held against tanks and paratroopers.
By mid-February 1945, the rest of the division had arrived and the full Rainbow entered the line. What followed was almost continuous forward movement including aggressive patrolling in the Hardt Mountains, a night assault through terrain that required pack mules for supply, a breach of the Siegfried Line that the Germans had believed impassable.
The cities came quickly after that. Würzburg in four days of house-to-house fighting, the Germans tunneling back through cleared ground to force the Rainbow to take the same buildings twice. Schweinfurt. Fürth. Nuremberg, and eventually Munich - the birthplace of the Nazi movement.
On April 29, the Rainbow reached Dachau.
“The GIs who liberated the camp looked like gods to us.”
Ben Lesser, survivor of Dachau
The Rainbow Division Liberation of Dachau Concentration Camp
The soldiers who liberated Dachau found more than 30,000 prisoners, and rail cars full of the dead, transported from other camps as the Reich collapsed, arriving with nowhere left to go. The living who no longer resembled the living. Men who had spent years inside this place looking out at soldiers who, to survivor Ben Lesser, looked like gods.
The Rainbow Division rabbi, Eli Bohnen, who entered the camp, wrote to his wife that night: nothing you can put in words would adequately describe what I saw.
Dachau had opened in March 1933, a precursor for the terrorizing system that would eventually consume millions of lives. The men of the Rainbow were among the first Americans to stand inside it on the day of liberation. What they saw there clarified, for many of them, everything they had endured to arrive at that moment.
The Division moved on to capture Munich, then into Austria for occupation duty.
They had covered hundreds of miles and had taken nearly 60,000 prisoners. From their commitment to combat on Christmas Eve 1944 to the end of the war, 135 days, the Rainbow was in combat for 106 days. 687 Rainbow men gave their lives.

A Journey With the 42nd “Rainbow” Infantry Division:
Standing at the gates of Dachau in 2015, I unknowingly began what would become more than a decade of intensive research into the 42nd "Rainbow" Division, the American soldiers who liberated this site on April 29, 1945.
That moment has since grown into an archive of documents, photographs, letters, oral histories, and materials contributed by veterans, their families, fellow historians, and official repositories across two continents. It is a living collection that continues to grow.
By 2017, I had interviewed my first Rainbow Division veterans. Among them was Lockered "Bud" Gahs. A friendship that became the beating heart of my work, his firsthand accounts anchoring this project in something no archive can provide: the voice of a man who was actually there.
Over the years, the relationship produced countless hours of interviews, two trips back to Europe together: to Alsace, where Bud stood at the exact house in Schweighouse-sur-Moder where he had held his position alone for hours during Operation Nordwind; to Épinal American Cemetery, where he stood at the graves of his fallen comrades for the first time since the war; and to the Dachau Memorial.
Max Lütgens (Dachau Education Department), Joseph Alexander (survivor), Erin Faith Allen, Abba Naor (survivor), Lockered ‘Bud’ Gahs (liberator) and Dr. Christoph Thonfeld (Director of Research, Dachau) at the 78th commemoration of the Liberation of Dachau.
In August 2022, Bud received the Legion of Honor from the French government on the ground where he had fought 77 years earlier.
On April 29, 2023, exactly 78 years after the liberation, Bud sat across from 45th Division veteran Dan Dougherty at Dachau and they told each other, for the first time, what they had seen that day. That conversation, captured on film, became one of the most significant documented moments we shared together.
To truly understand their experiences, my research has taken me back and forth across Europe, walking the same ground these soldiers traversed, from the frozen forests of Alsace where they faced their baptism of fire in Operation Nordwind, to the ruins of Würzburg where they fought house-to-house, to the solemn grounds of Dachau. Each site visit deepens my understanding in ways archive work alone cannot provide.
Through photography, film, and careful documentation, including relationships with locals who carry their own piece of this legacy, I preserve and reconstruct the physical and emotional context of stories that would otherwise exist only on scattered paper.
My research centers on the individual soldiers who wore the Rainbow patch: their hopes, fears, and the bonds that sustained them through one of history's darkest chapters.
