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 (Dambusters Raid ). 19 British Lancaster bombers from Royal Air Force 617 Squadron aimed to destroy the Möhne, Eder, and Sorpe dams using “Upkeep” bombs, designed to skip across water and sink against the dam wall. The Möhne and Eder dams were breached, releasing massive floods. The Sorpe dam sustained little damage.
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.
Forced labor was used to reconstruct the arch destroyed in the floodwaters of the Dambusters Raid, but then in 1945, the Wehrmacht demolished two of the Viaduct’s arches to hinder Allied advances.
The three battalions of the 75th Infantry Division continued to press south towards the Ruhr River. Every yard was bitterly contested by the German enemy whose freedom of movement was limited and compressed on all sides. German troops were hopelessly trapped and were being fired upon by artillery from all sides. The American foot troops continued to press forward three abreast. The Germans were attempting to prevent the Americans from capturing a main road that could offer an escape route across the Ruhr River.
The 2nd Battalion found resistance weakening, and they took advantage of this to drive south through to the Ruhr River. E- Company of the 2nd Battalion wrestled their objective from the enemy. My father 1st Lieutenant Arthur Thorspecken was in the 1st Battalion which found it’s sector crumbling and they reached the Ruhr without major difficulty.
The 3rd Battalion encountered stiff resistance from Germans who had entrenched themselves on the opposite slope of a hill slightly north of the river with the intention of defending that high ground at all cost. As elements of the 3rd Battalion advanced toward the hilltop, F-Company of the 289th Infantry Division, pushed through on the enemy right flank, catching the enemy in a deadly cross fire.
The German positions collapsed and the advance continued to Herdecke with the enemy fighting a delaying action as they retreated. An airstrike was made on the town of Herdecke, and the city was offered an opportunity to surrender by L-Company. The offer was accepted and K and L Companies crossed the Ruhr River on the south side of the town.
The 290th Infantry Division was relieved on April 14, 1945 by elements of the 313th and 314th Infantry in what would prove to be the final battle action in the European Campaign.
