On April 19, 1945, my father, 1st Lieutenant Arthur Thorspecken and his C-Company of the 75th Infantry Division were relieved by elements of the 313th Infantry Division. The 75th was then trucked to several locations in the Ruhr Valley for reassembly, and then sent to Iserlohn Germany. The town east of Iserlohn was Hemer which was the site of Stalag VIA, a large POW Camp. Rather than fighting a battle after the successful capture of the Industrial Ruhr Pocket, the 75th was now tasked with occupation duty.
On the evening of 13 April 1945, the United States Army began bombing the city of Iserlohn Germany. The bombing continued for three days. The bombardment lasted nearly three days but caused only minor damage.
The events of WWII are indelibly etched in the minds of the residents of Iserlohn who lived through the years of the Nazi inhuman racial ideology. The Nazi drive for conquest and annihilation cost countless lives. The exact number of Iserlohn residents who lost their lives due to Nazi doctrine are unknown. Municipal statistics report 776 fallen soldiers and 137 civilians killed by air raids and artillery fire. These numbers do not account for those who died in captivity, nor the number of Jewish residents who were deported from Iserlohn and murdered in concentration camps.
A synagogue was built in Iserlohn in 1829. It was destroyed on the Night of Broken Glass November 9, 1938. The building had to be demolished. The first Jewish deportation began on October 28, 1938. In 1941 the Jewish community that remained was moved to Kluse 18 and deported from there to to the industrial extermination camps of Auschwitz and Theresienstadt Germany.
Because of its metal industry, Iserlohn produced war-relevant products, including brass components, specialized light metal castings for ammunition, and hardware for Stick hand grenades. With every industrial building converted for armaments production. The town was a prime target for Allied bombing.
Iserlohn was therefore a prime target of Allied Air Strikes. The need to take protective measures for the population became apparent by 1943. Construction of the air-raid shelter tunnel under the Supreme City Church began at the end of 1943. This church is an emblem of the city of Iserlohn and also part of its coat of arms. The Supreme City Church in Iserlohn, which dates back to roughly 1350, survived the destruction of World War II.
With an originally planned length of 500 to 550 meters, the air raid shelter was supposed to be able to accommodate up to 6,600 people. By the end of the war, the tunnel had only reached a length of around 200 meters offering refuge for 2,000 residents.
Iserlohn was home to 5 military barracks and other military installations. The old style half-timbered homes were particularly vulnerable to Allied incendiary bombings. The town had 46,000 residents in 1943.
Prisoners of war from Stalag VI-A in Hemer Germany were used for construction. These same workers were not allowed to enter the tunnel during the Allied air raid attacks. Jews were also prohibited from entering the shelter. The Forced Laborers, many of them Russian and Polish, were literally worked to death. The forced laborers were expected to drill and chisel into the rock for 5 meters a week. Drilling operations had to stop due to the appearance of fissures and cracks in the clay. The loose clay and slate offered unreliable protection against bombings. With only room for one third of the residents, fights broke out for the right to enter the tunnels, resulting in overcrowding.
At midday on April 16, 1945, in Iserlohn, a Jagdtiger Tank Battalion led by Wehrmacht commander Albert Ernst, assembled for its final roll call before surrender to the U.S. 99th Infantry Division. American Major Boyd McCune lead the negotiations, which were eased by the fact that Ernst spoke English . The Germans lay all their weapons on the pavement of the Iserlohn city market square as the Americans watched.
The air raid shelter construction ended on April 16, 1945 when American forces occupied the city.

By mid April, 1945, the Ruhr factories were silenced. Thousands of German prisoners filled the Allies’ compounds. Elements of the German army were retreating further east. Concentration camps were discovered and liberated. The indescribable conditions at these camps shocked the world.
Most cities seen by C-Company soldiers were completely demolished. The Allies encountered pockets of German resistance in the drive to the Ruhr industrial complex. Hundreds of German soldiers were captured daily. Many were teenagers. Others were much older—in their sixties or more. These young and old, made up the untrained German people’s army. Conscripted soldiers from occupied nations were glad to be captured. They were aware a prisoner of war of the Allies was assured of food and shelter—much better than being a weary and starving German soldier.
The water supply for Herdecke Germany would be influenced by the Ruhr River and managed by the Ruhrverband corporation. In 1935, during the Nazi era, the organization was brought into line with Nazi ideology and placed under the authority of the Reich Office for Spatial Planning. Key infrastructure, such as the Hengsteysee reservoir, played a role in regional water management, with strict quality standards adhering to German drinking water regulation. The heavy Allied bombing of the city likely damaged the water supply.
On a small scale, American soldiers purified water using portable Halazone chlorine tablets for individual canteens. In this way, each soldier was responsible for purifying his own water supply. Halazone tablets were commonly used during World War II by U.S. soldiers for portable water purification, even being included in accessory packs for C-rations.
At the little town of Herdecke Germany, the burgomeister formally declared: “I surrender the town of Herdecke to the Allied Military forces at 1000 April 14, 1945. It is understood that from this time forward, control of Herdecke will be by the Allied forces.”
Albert Vögler, a prominent industrialist and Nazi supporter, committed suicide while being led away by American soldiers from his luxurious Hause Ende Ville in north Herdecke. He bit down on a hidden cyanide pill, dying instantly. Despite his death, he was still identified as one of the defendants in the Nuremberg trials of prominent industrialists, which prosecuted the group of businessmen who helped Hitler. The industrialists were tried at Nuremberg, for using slave labor, plundering occupied territories, and aiding the Nazi war machine. Most received prison sentences ranging from 2 to 12 years, though many were released early in the 1950s.
The Ruhr River-Viaduct was opened in 1879 as part of the Düsseldorf-Derendorf–Dortmund South Railway, In May 1943, it was damaged by a flood wave following Operation Chastise (
The devastating floodwaters traveled down the Ruhr river, impacting several towns and villages downstream in the Ruhr Valley, including the area surrounding Herdecke Germany, which is situated on the Ruhr between the Sorpe dam and the Rhine. The flood wave swept away a pillar of the viaduct, narrowly missing an approaching train. The destruction caused massive, though temporary, damage to water, power, and industrial infrastructure in the region. Over 1,600 people died in the flooding, a significant portion being allied prisoners of war and forced laborers.
The Ruhr River was the final objective of the 75th Infantry Division. When the 75th reached this objective they had split the surrounded German troops in half and finally crushed the Industrial Ruhr Pocket. The Berger Memorial sits high on a hillside overlooking on a particularly beautiful section of the river Ruhr River between Wetter and Witten Germany. The memorial was built between 1902 and 1904 to honor Louis Constanz Berger, (1829-1891), an industrialist and community co-founder. Its construction occurred during a period of industrialization and modernization of the Ruhr region. I imagined that my father 1st Lieutenant Arthur Thorspecken and his C-Company might have come to this overlook to view their final objective. The memorial would have stood at this spot in April of 1945, having been built between 1902 and 1904,
During WWII, the Krupp steel works in Essen, led by Alfried Krupp from 1943, were the cornerstone of the Nazi war machine, producing artillery, tanks, and u-Boats. Despite massive Allied bombing, the works managed to remain standing until 1945. The firm heavily utilized over 100,000 forced laborers,
After my failed attempt to sketch remnants of a Forced Labor Camp in Witten-Annen Germany, I decided to sketch the Zeche Nachtigal which is now a museum. I figured that the forced laborers who were not working in the Annen Steelworks Factory building weapons, would be at Nachtigal. Nachtigal means nightingale which is a bird known for or its powerful, complex, and beautiful song, which is often heard at night.
A satellite camp of Buchenwald was established is Annen–Witten. My late night research found a memorial which had some of the foundations of barracks visible and several plaques to memorialize what had happened on the site. By using Google Street View I actually was able to see the memorial right from where I might be able to park the rental car. It was rare for me to actually see my destination so I was excited.
On September 17, 1944, the first train for the Annen Cast Steelworks containing 700 prisoners arrived from Buchenwald concentration camp. There is evidence that there were 71 Poles among those camp prisoners whose names are known. The camp was similar to many other satellites of concentration camps with regard to its structure, furnishings and living conditions. It consisted among other things of several barracks to house the prisoners and a muster ground and was surrounded by a double layer of barbed wire to prevent the prisoners from escaping. The furnishings were extremely sparse and were largely limited to two-story bunk beds. In addition, the washroom barracks had not been completed when the first inmates arrived, so that they had to wash in the open air. In Witten-Annen, as elsewhere, forced laborers were subject to violence and harassment from the functionary prisoners and the SS guards and suffered from hunger and disease due to malnutrition, the cold temperatures and inadequate hygiene.
Düren is a quarter in Witten Germany just south of Dortmund. Rather than being a town, it is really just farm land. I parked on the side of a muddy farm road and hiked to a trail. That trail made its way along the edges of farm fields at the edge of the woods. A small stream separated the trail form the fields. I jumped the stream and set up to sketch at the edge of a farmers field. I worked quickly, but as I sketched it started to rain. The drops splattered on the page. A German woman was walking her dog on the trail She waved, but must have thought I was crazy to be sketching in the rain.
During the WWII, there were a total of around 24,900 forced laborers from all the occupied territories in the area now covered by the town of Witten. On average, they worked for approximately 15 months in the town, and made up the majority of the workforce there. At the beginning of 1945, for example, the forced laborers constituted about 55 % of the total workforce in Witten. The different areas of work that they performed meant that large-scale forced labor camps were needed. As a result, it is thought that between 230 and 250 forced labor camps of different sizes were established in the town during that period.
The 75th Infantry Division, 1st Battalion moved south with the other 2 Battalions against heavy last ditch German opposition on April 11th, 12th and 13th. My father, 1st Lieutenant Arthur Thorspecken lead C-Company as part of the 1st Battalion was part of this attack. They advanced towards Witten Germany and encountered stiff resistance as they neared the objective. They broke up a large scale counterattack with mortar and artillery fire. They then had to fight a fierce house to house battle through Witten to advance to the Ruhr River.
At the beginning of 1945, for example, the forced laborers constituted about 55 % of the total workforce in Witten. The different areas of work that they did meant that a large-scale accommodation was needed. As a result, it is thought that between 230 and 250 forced labor camps of different sizes were established in the town during that period.
