In December 1944, a man in an American captain’s uniform walked into a Third Army headquarters near Luxembourg City. He identified himself as Chaplain Captain Andrew Whitfield of the 28th Infantry Division, a Methodist minister separated from his unit during the German breakthrough in the Ardennes.
He spoke with a soft Southern drawl and carried a black leather Bible. He told a moving story of a circuit-riding upbringing near Nashville and asked for a warm meal and a place to sleep. Within an hour, he was dining with staff officers and asking precise questions about lines of communication.
The man was actually SS Hauptsturmführer Manfred Roeder, a 31-year-old German operative from Munich. He had spent a year at a seminary in Ohio in the late 1930s to perfect his English and learn American religious customs. He was part of Otto Skorzeny’s Operation Greif, a unit trained to wear American uniforms and operate behind Allied lines.
Roeder had already infiltrated two American command posts earlier in the offensive. He carried forged papers and wore a uniform taken from a dead American captain. His cover seemed flawless.
The chaos of the Ardennes offensive created ideal conditions for such infiltration. Communication lines were cut, units were scattered, and rear-area security was often relaxed. Disguised German commandos were shifting road signs, cutting wires, and gathering intelligence.
At the headquarters, Roeder’s presence drew the attention of Captain Daniel Stein, a Jewish-American chaplain from Brooklyn. Stein sat down across from him and began a casual conversation. He asked which regiment Roeder was with and whether he had encountered a specific chaplain in the sector.
Roeder answered smoothly. Then Stein asked about his theological training. Roeder said he had studied at the Vanderbilt School of Religion, class of 1938.
Stein paused. He knew Vanderbilt had not established an independent divinity school under that name until later. He excused himself and reported the discrepancy to the command office. The report reached General George Patton within the hour.
Patton arrived at the headquarters unannounced and confronted the man directly. He asked how a Nashville Methodist would explain justification by faith to a frightened private. Roeder gave a polished answer.
Patton then asked him to offer a brief prayer in Latin, specifically the Paternoster. Roeder hesitated for a fraction of a second. He bowed his head and began reciting the Lord’s Prayer.
He made a grammatical error. He said “ad venerat” instead of “adveniat.” Patton slammed his hand on the desk.
Patton pointed out that a trained scholar would not invent a past perfect tense in the Lord’s Prayer. He accused the man of being a German saboteur wearing a dead man’s uniform. Roeder dropped the accent and admitted his real identity: Hauptsturmführer Manfred Roeder of Skorzeny’s SS brigade.
Military police stripped the chaplain crosses from his collar and confiscated the Bible. Roeder was taken to a maximum-security interrogation facility. Over six hours, he provided details about Operation Greif, including supply dump locations and radio frequencies.
That information allowed American patrols to capture twelve other disguised German operatives across the sector before the night ended.
Captain Daniel Stein returned to Brooklyn after the war. He served as a rabbi in Crown Heights for forty years and often told his students the story of the fake chaplain. He taught them that asking an unexpected question reveals the truth in an unguarded moment.
Roeder survived the war and was released from Allied custody in 1948. He later became a journalist in Munich and published a memoir in 1962 titled *I Failed at the Lord’s Prayer*.
Patton never made a public statement about the incident. He did write a single line in his diary that evening: “A good cover is always built on what the cover lacks, not what it has.”
Historians have debated whether Patton’s linguistic trap was too risky. Some argue that a genuine American chaplain under stress could have made the same mistake. Others maintain that the threat from Operation Greif required immediate and decisive action.
What is certain is that the exposure of the infiltrator secured the headquarters and helped dismantle the sabotage network.
