Frohlinde means Joyful in German. The plague cross, known locally as the Bookenkreuz, dates back to the time of the Thirty Years’ War, when the plague raged (1618 and 1648). The farming communities of Frohlind95h e, Obercastrop, and Rauxel, as well as other surrounding villages, erected plague crosses and obligated themselves to hold annual processions to these crosses and distribute alms, bread, money, and other donations to the local poor.
While the 291st Infantry Division was attacking Castrop-Rauxel Germany, my father, 1st Lieutenant Arthur Thorspecken, was leading his C-Company of the 290th Infantry, 75th Infantry Division, into Frohlinde. Heavy 75th Infantry artillery and air bombing was aimed at the city before the attack, effectively leveling the city.
All Allied units had been ordered by XVI Corps to attack south to the Ruhr River as quickly as possible. What resulted was that all the allied units raced against one another in their dash to the objective. This race to the objective resulted in some chaos as units surged forward without being aware of the progress of units to their left and right. The result could be units separated and isolated behind enemy lines.
On entering a city and seeing the type of fighting needed, the Company Commander should have given his platoons very definite zones of operation. That platoon zone should have then been broken down into individual squad areas. Only then could mopping up operations be successful in a Company zone. In the heat of battle, however, such strategic planning can fall apart.
A definite front line can evaporate, with some units pushing forward quickly while others might be stopped or delayed by heavy enemy resistance. Communication between companies could be problematic, with radios down or a messenger delayed in delivering a message.
The overall objective of General Ray Porter’s 9th Army Group was to drive east after crossing the Rhine River, and then attack south to defeat the estimated 370,000 German defenders trapped in the Ruhr Pocket. Dortmund Germany was the largest industrial City in the area of attack and Frolinde was on the north West outskirts of Dortmund.
According to the XVICorps estimate, the 75th Infantry would face the veteran 116th Panzer Division’s 16th Panzer Grenadier Regiment. The Germans could convert the villages, cities, and industrial plants into strong points to delay the advance.
Useful information was gained from prisoner of war interrogations. Interrogation teams faced a torrent of German prisoners with more than 3,600 passing through the division’s cages. From this flow came a large amount of all kinds of information, including the insight that the Germans planned to continue delaying actions, withdrawing after the first significant contact.
Major General John B. Anderson, the XVI Corps commander, commended the 75th Infantry Division for its “aggressive patrolling, constant observation, and the activities of [its] intelligence agencies.”

On April 7, 1945, the 291st Infantry of the 75th Infantry Division faced increasing fire from snipers and 120mm mortars. I have come to the conclusion that my father’s 290th Infantry Division didn’t enter Castrop-Rauxel because they were busy liberating the towns of Frohlinde and Kirchlinde Germany. The battle faced by the 291st Infantry is however right in line with what my father, 1st Lieutenant Arthur Thorspecken might have faced in the Ruhr.
Erin Shaft 7 is located right outside of downtown Castrop-Rauxel Germany. Next to this are several new office buildings that have a very modern steel beam grid on the facades that blend well with the industrial look of the mine. The Erin Schacht shaft was sink in 1951, so it is a post World War II coal mine shaft. 68-meter-high Dörnen-type head frame became a landmark of Castrop-Rauxel and was preserved as an industrial monument after the mine’s closure in 1983.
