Operation Blackcock was an operation to clear German troops from the Roer Triangle, formed by the towns of Roermond and Sittard in the Netherlands and Heinsberg in Germany during the fighting on the Western Front in the Second World War. It was conducted by the British Second Army between 13 and 26 January 1945. The objective was to drive the German 15th Army back across the rivers Roer and Wurm and move the frontline further into Germany. The operation was carried out by Lieutenant-General Neil Ritchie's XII Corps by three divisions: the 7th Armoured Division (Major-General Lewis Lyne), the 43rd (Wessex) Infantry Division (Major-General Ivor Thomas) and the 52nd (Lowland) Infantry Division (Major-General Edmund Hakewill-Smith). The operation, named after the Scottish male black grouse, is relatively unknown.^[1]

Dispositions along the Roer Front

By the end of 1944, the frontline in Dutch Limburg was stable along several natural barriers. The most difficult barrier to cross was the River Maas running along the Dutch–Belgian border. The next barrier was the River Roer, running from the German Eifel area through Heinsberg towards Roermond, where it joins the Maas. From Heinsberg, southwards the Siegfried Line or 'West Wall' was formed along the banks of the Rur. Dutch South-Limburg was already liberated in September by the First United States Army, but the area above the Sittard–Geilenkirchen line was still in German hands. Here, the front had settled along the "Saefeller Beek", a small creek that also seemed difficult to surpass. These obstacles formed a triangular area, referred to as the Roermond Triangle, which protruded into the frontline like a bulge. As a result of the German offensive in the Ardennes (the Battle of the Bulge), the Allies withdrew resources to stop the German advance in the American First Army's sector. Therefore, the British Second Army's XII Corps guarded the frontline north of Sittard for the US Army. The Maas front was guarded by the British VIII Corps.

The British XII Corps was facing the German XII SS Corps, commanded by Günther Blumentritt, which had two infantry divisions present along the frontline between Geilenkirchen and Roermond. In the Roermond area these divisions were strengthened by the Fallschirmjäger-Regiment Hübner.

Blackcock

The clearing of the Roer Triangle was planned along three axes. The left axis, formed by the 7th Armoured Division, was aimed at capturing the bridge across the Roer in Sint Odiliënberg (51°8′55.9″N 6°0′12.6″E / 51.148861°N 6.003500°E / 51.148861; 6.003500 (Sint Odiliënberg)). For the 7th Armoured Division, the operation would start with bridging the creeks south of Susteren. The centre axis, formed by the 52nd Infantry Division, was aimed at the capture of Heinsberg. In order to do this, a break-through at the German defence line was to be undertaken near Hongen in order to open the road between Sittard and Heinsberg for moving troops. The right axis, formed by the 43rd Infantry Division, was aimed at clearing the area south-east of Dremmen. This axis would use the break in the German defence line that was to be created by the Lowland Division.

Hübner's defeat at Sint Joost

The Battle for the Dutch village of Sint Joost was a turning point in Operation Blackcock. After four days of fighting, the Germans knew that the armoured division that was facing them relied heavily on the roads to manoeuvre their vehicles, especially due to poor winter conditions. The small village of Sint Joost was on the route of the 7th Armoured Division's drive north towards Montfort.

On 20 January, infantry and cavalry units of the Desert Rats launched a first attack on the (assumed) two German companies of the 2nd Battalion Fallschirmjäger Regiment Hübner in Sint Joost. It took four attacks to clear the village, the final assault taking place on Sunday, the 21 January.

In total, sixty Fallschirmjäger were taken prisoner. The 9th Durham Light Infantry and 1st Rifle Brigade suffered heavy losses in Sint Joost. The DLI suffered 33 casualties, of which eight were killed in action. The Rifle Brigade counted 34 casualties, of which three men from I Company were killed in action. More than one hundred German soldiers died. German paratroopers who were not killed only left the cellars under civilian cover, afraid that they would be shot by the victors. Hübner had lost one company and a second had been nearly destroyed.

Aftermath

The operation was a success for the Allies since all its objectives were met. The German divisions were thrown out of the Roer Triangle except for the area immediately south of Roermond. Here, Hübner's paratroopers stayed in control. The 52nd Lowland British Division fought the toughest battles and received 752 casualties. Of these, 101 were killed. 258 soldiers were transported from the front because of sickness, mostly as a direct result of the adverse weather conditions. The 7th Armoured Division counted just over 400 casualties. The Desert Rats' losses in vehicles were rather light, with only 20 tanks knocked out by the enemy and a further 23 broken down due to mechanical problems. Of the knocked-out tanks 10 were damaged beyond repair. The number of German casualties was approximately 2,000. During the operation, 490 prisoners were taken by the Desert Rats, amongst them were six officers. The Lowland Division took more than 1,200 prisoners, the Wessex Division took some 400 soldiers captive.

Once Operation Blackcock was completed, the plans for the capture of the Rhineland could commence. Operation Veritable, by the First Canadian Army, was launched on the 8 February and was aimed at breaking through the German defences in the Klever Reichswald, some 60 km (37 mi) north of the Roer Triangle. Operation Grenade, the southern part of the pincer movement, by the US Ninth Army was launched on 23 February. General William Hood Simpson's US Ninth Army crossed the river Roer south of Heinsberg in the early hours of 23 February 1945. Twelve hours later Simpson had 16 battalions on the east bank, together with seven heavy bridges, and several light assault bridges. American losses were light on the first day; 700 prisoners were taken. A task force was formed by Ninth Army's XVI Corps which rushed towards Venlo to meet up with the British in the north. On 1 March Roermond was captured by the reconnaissance troop of the US 35th Infantry Division (the "Santa Fe" Division) without a single shot being fired.
