Operation Plunder

Operation Plunder. This was the Allied military operation to force a crossing of the River Rhine in late March 1945, marking the final major assault into the heart of Nazi Germany. Planned under the overall command of Field Marshal Bernard Montgomery, it involved the British Second Army and the U.S. Ninth Army launching a massive amphibious and airborne assault. The successful operation breached the last major natural barrier guarding the German Reich, leading to the rapid advance across the North German Plain.

Background and planning

Following the conclusion of the Battle of the Bulge and the subsequent Allied advance from Paris to the Rhine, the Western Allies stood poised to cross the final major obstacle into Germany. The Supreme Headquarters Allied Expeditionary Force (SHAEF), under General Dwight D. Eisenhower, assigned the main crossing effort to 21st Army Group, commanded by Montgomery. The plan, developed meticulously after the capture of the Ludendorff Bridge during the Battle of Remagen, called for a set-piece assault across the Lower Rhine near the towns of Rees, Wesel, and Village. This operation was designed to complement the smaller-scale crossings further south by General George Patton's U.S. Third Army. Opposing the Allies was Army Group H, led by Johannes Blaskowitz, with the formidable First Parachute Army under Alfred Schlemm manning defensive positions along the river.

The crossing of the Rhine

In the evening of 23 March 1945, after one of the largest artillery bombardments of the Western Front, Allied forces commenced the assault. The British Second Army, led by Lieutenant-General Miles Dempsey, crossed north of Wesel using a vast array of amphibious vehicles, including Buffalo amtracs and Landing Craft. Simultaneously, the U.S. Ninth Army under Lieutenant General William H. Simpson crossed south of the city. To secure the flanks and disrupt German reinforcements, the massive airborne operation Operation Varsity was launched at dawn on 24 March, involving the British 6th Airborne Division and the U.S. 17th Airborne Division. These paratroopers landed east of the Rhine, engaging elements of the Wehrmacht and Luftwaffe field divisions around Hamminkeln and the Diersfordter Wald.

Allied operations and battles

The link-up between the ground forces from Operation Plunder and the airborne troops of Operation Varsity was achieved rapidly, though not without intense combat. Key engagements included the capture of the shattered city of Wesel by British Commandos and troops from the British XXX Corps, and the fierce battle for the town of Rees involving the 51st (Highland) Division and German paratroopers. To the south, the U.S. XVI Corps expanded its bridgehead, fighting units from the XLVII Panzer Corps. The rapid establishment of Bailey bridges and the use of amphibious DUKW trucks by the Royal Engineers and U.S. Army Corps of Engineers allowed a massive buildup of Sherman and Churchill tanks, breaking through the German Siegfried Line defenses east of the river.

Aftermath and significance

The success of Operation Plunder and Operation Varsity utterly collapsed German defenses on the northern Western Front. This victory allowed the British Second Army to spearhead a drive towards the North German Plain, advancing on key objectives like Bremen and Hamburg, while the U.S. Ninth Army wheeled south to form part of the encirclement of the Ruhr Pocket. The operation is historically significant as it represented the last major opposed river crossing in World War II in Europe and demonstrated unparalleled Allied coordination between infantry, artillery, engineers, and airborne forces. It paved the way for the final thrusts that led to the link-up with the Soviet Red Army at the Elbe and the ultimate collapse of Nazi Germany.
