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.
I sketched the historic twin engine winding machine. It is roughly the same size as the steam engine used previously in operation starting in 1871. It was used to hoist coal from the Hercules shaft. As the shaft was deepened a stronger winding machine was needed. In 1892 the coal mine shut down due to flooding. The machinery was sold off and soon the site became a brick works. By 1897 the brickwork’s produced up to eleven million bricks annually for the construction of industrial facilities and houses. The history of the brickwork’s jumped from 1897 to 1983. There is no mention of what happened at the brickwork’s during WWII, but it is safe to say the business would have been booming in war time.

Forced laborers were extensively used in German brick factories during WWII, particularly to produce building materials for Nazi construction projects. Concentration camp prisoners and millions of civilians from occupied territories were exploited by German industry to support the war effort, including the production of bricks. With over 200 forced labor camps in Witten it seems very likely that the forced labor would have been used in the Nachtigal brick factory. With the Ruhr area being constantly bombed by the allies there would have been a need of bricks to repair damaged buildings. Young eastern European men were obliged to join the German workforce, but both men and women were forcefully abducted from the streets.
Camp barracks in industrial centers varied in size, but most have been described by former forced laborers as poorly constructed, surrounded with barbed wire, and heavily guarded. The barracks were typically equipped with one small stove, a limited number of washrooms and toilets, mattresses filled with sawdust to make crude beds, and few blankets. Eastern Europeans working in factories, like the brickwork’s, received one cup of coffee or tea, 200-300 grams of bread, and one or two cups of watery cabbage soup per day. These rations, however, largely depended on what food was available, and as the war continued, food rations often decreased.
A sub-camp of the Buchenwald concentration camp was established in Witten on September 16, 1944, utilizing an existing barrack complex built in 1942 near the Dortmund-Witten railway line. The initial transport from Buchenwald Concentration Camp brought 700 male prisoners, primarily political detainees aged 16 to 63 from the Soviet Union, France, Poland, Czechoslovakia, Italy, Belgium, and Germany, with about one-third of a subsequent group of 50 arrivals in February 1945 being Polish Jews. These prisoners, housed in wooden barracks with double bunks and minimal facilities, performed grueling 12-hour shifts in Hall 7 of the Steelworks foundry, operating furnaces and machines to produce steel components for naval armor and aircraft, under constant threat of violence from SS guards and kapos.
A Kapo was a Nazi concentration camp prisoner—often a criminal or political prisoner—assigned by the SS to supervise forced labor or carry out administrative tasks, acting as a collaborator in exchange for privileges. They were hated by fellow inmates for their brutality and held authority over them, often enjoying better food and conditions.
The camp, secured by barbed wire and watchtowers, operated until late March 1945, with prisoner numbers fluctuating to around 600 by evacuation due to deaths, escapes, and returns to the main camp; the SS received four Reichsmarks daily per prisoner from the factory.
Conditions in the sub-camp were dire, marked by undernourishment, exposure to cold, disease, and brutal oversight by SS, leading to frequent accidents and illnesses like pulmonary infections. By late March 1945, at least 16 prisoners had died from exhaustion and related causes, with nine Soviet inmates secretly executed by transfer to Buchenwald’s crematorium and over 60 sick individuals returned to the main camp, of whom at least 14 perished shortly after.
On the night of March 29, 1945, the SS evacuated the remaining approximately 600 prisoners on a death march northeast toward Lippstadt Germany, to the west of Dortmund-Witten, during which an unknown number were killed; the survivors were abandoned on April 1 and liberated by advancing U.S. forces, with some succumbing to their ordeals in the following days. Post-liberation investigations in the 1960s and 1970s examined SS crimes at the site but resulted in no convictions. Most Germans kept silent about the crime of forced labor or completely denied it.
Holocaust survivor Irene Weiss put it this way, “The most dangerous animal on earth is man. A man can turn into animal in no time. All he needs is permission. As soon as permission is given from government, it accelerates. Even a hint of permission that it is OK to attack this group or exclude this group, or shame that group. It’s happening, it never stopped.”

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.

I went for a walk in the Dorney Wald Nature Preserve. It was raining all day. I parked in a ball park parking lot and waited for the worst of the rain to stop. Then I ventured out in search of a statue of two German soldiers. I walked for miles and could not fin them. I finally gave up and when I got back to the car. I started searching for a place to eat. The place I found was right on the opposite sided of the forest within walking distance. I decided to walk over to get a gyro to eat. On that walk I ended up stumbling upon the statue I ad been searching for.
“The Nazi regime of forced labor was a crime that made people throughout Europe slaves of the German war and business interests,” emphasized Günter Saathoff. “In contrast to the extermination camps in the east, the German population could not claim that they did not know anything about it because the wrongs were committed before their very eyes. Nevertheless, it was later denied or played down as a concomitant of war and the occupiers’ rule.
Dorney Germany is a four road town just to the south of Dortmund. The 75th Infantry Division continued it’s attack south throughout April 9th and 10th with the 2nd Battalion capturing Oespel and Dorney then proceeding south to the regimental objective which ultimately would be the Ruhr river.
In entering one room in the Dortmund Forced Labor Camp, soldiers found 4 dead babies lying on a table covered with sheets. On the floor were naked skeletal men and woman also covered in sheets. Babies were systematically taken from Forced Labor women and then starved to death to satisfy the the German ideal of the final solution. If the woman did not get right back to work, she would be murdered as well. If a woman tried to recover her child from German custody, she would be shot.
It started to rain as I sketched. Rain drop blasts littered the surface of the sketch. I could not protect the page. I closed the sketchbook and sat as it rained, thinking it might stop. I was sheltered in a rain jacket. I finally gave up and put the sketchbook away. After walking half way out of the cemetery, the rain stopped. I went back to my spot and sketched again quickly. I managed to cover the page before another wave of rain started. As I was leaving, I noticed a headstone for Fritz and Gerta Torspecken. My last name is Thorspecken and in America that is quite unique. With just one letter missing, I thought these might be long lost relatives. I know that my original ancestor, Dr. Elias Julius Thorspecken emigrated to America in 1830 or so to build a new life. He served his new country as a doctor during the Civil War. Arolsen Germany the city that Augustus left, is just 142 miles due west. This headstone left me thinking that I might have deep roots in this area of Germany.
As Allied troops along with my father, 1st Lieutenant Arthur Thorspecken who was leading C-Company of the 1st Battalion of the 75th Infantry Division, were attacking Dortmund Germany and moving south, the German Gestapo were looking to hide atrocities before they retreated.
Hundreds of thousands of forced laborers were exploited in the armament factories and coal mines around the Ruhr River during the Second Word War. An estimated 30,000 forced laborers were deployed in Dortmund during the Second World War. They were accommodated in about 300 camps, one of those being a branch of the Buchenwald concentration camp.
In Dortmund Germany, I searched for an old building that might have stood back in 1945. The Altes Stadhaus was hosting a wedding when I stopped to sketch. People were gathered outside at the entrance to the building despite the intermittent rain. A woman released a metallic helium balloon and people cheered as the balloon floated up to the grey sky. I hunched over my drawing trying to block the rain before the page became a liquid mess. Saint Reynolds Church could be seen down the street.
On April 12, 1945, the 95th Infantry Division attacked attacked Dortmund from the southeast and liberating the central and southern part of the city. Edward D. Snell, in F-Company, 2nd Battalion, 378th Regiment, said he couldn’t believe how much of the city was destroyed by years of bombing. There was nothing left of the center municipality of Dortmund, it was completely gutted.
