The Pine Grove Furnace Prisoner of War Interrogation Camp was a covert World War II installation situated in southern Pennsylvania, selected due to its closeness to Washington, DC. Active between 1943 and 1945, it focused on interrogating German POWs. Remnants of the site still exist today.
Following the war, the location was transformed into Camp Michaux, a youth camp operated by the United Presbyterian Church alongside the Evangelical and Reformed Church.
Location
Positioned in Cumberland County, Pennsylvania, the camp lies near South Mountain within the boundaries of Michaux State Forest. It occupied land along High Mountain Road (which was later renamed Michaux Road), covering an area of about .
The Pine Grove Furnace interrogation facility was situated close to Camp Sharpe, a separate World War II POW labor camp.
Early history
Prior to its use as a POW camp, the site was known as Bunker Hill Farm, encompassing roughly . In the 1700s, the discovery of iron ore combined with plentiful forests supported a thriving iron industry centered around the Pine Grove Iron Works, which eventually became part of the South Mountain Iron Company. At its height, these operations extended over approximately .
By the late 1800s, as iron production waned, the South Mountain Iron Company sold this property to Pennsylvania’s Commonwealth in 1912. The land was then designated as a state forest reserve with sections allocated for agricultural purposes.
CCC Camp
On May 22, 1933, the U.S. Government inaugurated the Pine Grove Furnace Civilian Conservation Corps Camp (Camp S-51-PA), overseen by the U.S. Army and associated with CCC Company 329. This camp housed around 200 men who engaged in construction projects, forest stewardship, fire prevention, and educational activities across its site. With America's increasing involvement in World War II, interest in CCC initiatives diminished, culminating in Camp S-51-PA’s closure in February 1942.
POW interrogation camp
During World War II, the necessity for prisoner of war camps within the United States expanded as military authorities sought to gather critical intelligence from captives. The War Department identified Pine Grove Furnace’s secluded setting as optimal for secure interrogations while maintaining proximity to Washington, DC decision centers.
In December 1942, the War Department acquired the former CCC facility and began converting it into a POW interrogation center by February 1943. The Army Corps of Engineers oversaw construction based on designs by William S. Lozier, Inc. This installation operated alongside other interrogation sites such as Fort Hunt in Virginia and Camp Tracy in California.
The camp featured distinct sections for German officers, enlisted personnel, and subsequently some Japanese POWs. It became operational on May 20, 1943, and was referred to as the "3300th Service Unit" in unclassified records to ensure confidentiality. Command initially rested with Captain John F. Houck until Fall 1944 when Captain Lawrence C. Thomas took over; Thomas was fluent in German and simultaneously led Gettysburg POW Camp.
Guards were frequently soldiers who had been wounded in combat and reassigned to POW duties. The camp primarily served as an initial evaluation point where prisoners’ intelligence worth was assessed prior to relocation elsewhere. This temporary population—usually held from several days up to weeks—helped maintain security protocols and contributed to zero escape incidents.
Unlike conventional detention or detailed interrogation camps, Pine Grove Furnace specialized in categorizing prisoners according to their intelligence potential. Early detainees included members of the German Afrika Korps and U-Boat crews; later on, a limited number of Japanese prisoners were also held.
Treatment of prisoners complied with the 1929 Geneva Convention guidelines, ensuring adequate living space, nutrition, and recreational opportunities. Detainees participated in various activities consistent with security measures such as creating artwork—some pieces are preserved by the Cumberland County Historical Society—and individuals like Heinrich Backhaus went on to develop professional artistic careers after the war.
POW operations at the camp ended on November 28, 1948, after which control reverted to Pennsylvania’s Michaux State Forest authorities. Throughout its operation, approximately 7,500 German and 161 Japanese prisoners were processed through this distinctive interrogation facility.
Camp Michaux
On July 1, 1947, the Mercersburg Synod of the Evangelical and Reformed Church together with the Synod of Pennsylvania of the United Presbyterian Church leased the former Pine Grove Furnace POW Interrogation Camp site from the Commonwealth of Pennsylvania. They transformed the location into a permanent church youth camp, naming it Camp Michaux in honor of the adjacent Michaux State Forest.
Many of the original prisoner-of-war structures were preserved by the new operators, who also maintained displays featuring artwork created by former inmates. Despite these efforts, escalating upkeep expenses forced the camp to close permanently on December 31, 1972. Presently, the site’s historical value permits public visits to its remains, with the Cumberland County Historical Society providing a self-guided walking tour for visitors.
An archaeological survey conducted in 2020 at Camp Michaux revealed only a limited number of artifacts connected to its role as a WWII interrogation facility.
