Battle of Dunkirk
The Battle of Dunkirk was fought around the French port of Dunkirk during the Second World War, between the Allies and Nazi Germany. As the Allies were losing the Battle of France on the Western Front, the Battle of Dunkirk was the defence and evacuation of British and other Allied forces to Britain from 26 May to 4 June 1940.
After the Phoney War, the Battle of France began in earnest on 10 May 1940. To the east, the German Army Group B invaded the Netherlands and advanced westward. In response, the Supreme Allied Commander, French General Maurice Gamelin, initiated "Plan D" and British and French troops entered Belgium to engage the Germans in the Netherlands. French planning for war relied on the Maginot Line fortifications along the German–French border protecting the region of Lorraine but the line did not cover the Belgian border. German forces had already crossed most of the Netherlands before the French forces had arrived. Gamelin instead committed the forces under his command – three mechanized forces, the French First and Seventh Armies and the British Expeditionary Force – to the River Dyle. On 14 May, German Army Group A burst through the Ardennes and advanced rapidly westward toward Sedan, turning northward to the English Channel, using Field Marshal Erich von Manstein's plan Manstein Plan#Sichelschnitt, effectively flanking the Allied forces.
A series of Allied counter-attacks, including the Battle of Arras, failed to sever the German spearhead, which reached the coast on 20 May, separating the BEF near Armentières, the French First Army, and the Belgian Army further to the north from the majority of French troops south of the German penetration. After reaching the Channel, the German forces swung north along the coast, threatening to capture the ports and trap the British and French forces.
In one of the most debated decisions of the war, the Germans halted their advance on Dunkirk. What became known as the "Halt Order" did not originate with Adolf Hitler. Generaloberst Gerd von Rundstedt and Generaloberst Günther von Kluge suggested that the German forces around the Dunkirk pocket should cease their advance on the port and consolidate to avoid an Allied breakout. Hitler sanctioned the order on 24 May with the support of the Oberkommando der Wehrmacht. The army was to halt for three days, which gave the Allies sufficient time to organise the Dunkirk evacuation and build a defensive line. While more than 330,000 Allied troops were rescued, the British and French sustained heavy casualties and were forced to abandon nearly all their equipment; around 16,000 French and 1,000 British soldiers died during the evacuation. The British Expeditionary Force alone lost some 68,000 soldiers during the French campaign.
Prelude
On 10 May 1940, Winston Churchill became Prime Minister of the United Kingdom. By 26 May, the BEF and the French 1st Army were bottled up in a corridor to the sea, about deep and wide. Most of the British forces were still around Lille, over from Dunkirk, with the French farther south. Two massive German armies flanked them. General Fedor von Bock's Army Group B was to the east, and General Gerd von Rundstedt's Army Group A to the west. Both officers were later promoted to field marshal.Halt order
On 24 May, Hitler visited General von Rundstedt's headquarters at Charleville. The terrain around Dunkirk was thought unsuitable for armour. Von Rundstedt advised him the infantry should attack the British forces at Arras, where the British had proved capable of significant action, while Kleist's armour held the line west and south of Dunkirk to pounce on the Allied forces retreating before Army Group B. Hitler, who was familiar with Flanders' marshes from the First World War, agreed. This order allowed the Germans to consolidate their gains and prepare for a southward advance against the remaining French forces.Luftwaffe commander Hermann Göring asked for the chance to destroy the forces in Dunkirk. The Allied forces' destruction was thus initially assigned to the air force while the German infantry organised in Army Group B. Von Rundstedt later called this "one of the great turning points of the war".
The true reason for the decision to halt the German armour on 24 May is still debated. One theory is that Von Rundstedt and Hitler agreed to conserve the armour for Fall Rot, an operation to the south. It is possible that the Luftwaffe's closer ties than the army's to the Nazi Party contributed to Hitler's approval of Göring's request. Another theory—which few historians have given credence—is that Hitler was still trying to establish diplomatic peace with Britain before Operation Barbarossa. Although von Rundstedt after the war stated his suspicions that Hitler wanted "to help the British", based on alleged praise of the British Empire during a visit to his headquarters, little evidence that Hitler wanted to let the Allies escape exists apart from a self-exculpatory statement by Hitler himself in 1945. The historian Brian Bond wrote:
Whatever the reasons for Hitler's decision, the Germans confidently believed the Allied troops were doomed. American journalist William Shirer reported on 25 May, "German military circles here tonight put it flatly. They said the fate of the great Allied army bottled up in Flanders is sealed." BEF commander General Lord Gort, commander-in-chief of the BEF, agreed, writing to Anthony Eden, "I must not conceal from you that a great part of the BEF and its equipment will inevitably be lost in the best of circumstances".
Hitler did not rescind the Halt Order until the evening of 26 May. The three days thus gained gave a vital breathing space to the Royal Navy to arrange the evacuation of the British and Allied troops. About 338,000 men were rescued in about 11 days. Of these some 215,000 were British and 123,000 were French, of whom 102,250 escaped in British ships.
Battle
"Fight back to the west"
On 26 May, Anthony Eden told Gort that he might need to "fight back to the west", and ordered him to prepare plans for the evacuation, but without telling the French or the Belgians. Gort had foreseen the order and preliminary plans were already in hand. The first such plan, for a defence along the Lys Canal, could not be carried out because of German advances on 26 May, with the 2nd and 50th Divisions pinned down, and the 1st, 5th and 48th Divisions under heavy attack. The 2nd Division took heavy casualties trying to keep a corridor open, being reduced to brigade strength, but they succeeded; the 1st, 3rd, 4th and 42nd Divisions escaped along the corridor that day, as did about one-third of the French First Army. As the Allies fell back, they disabled their artillery and vehicles and destroyed their stores.On 27 May, the British fought back to the Dunkirk perimeter line. The Le Paradis massacre took place that day, when the 3rd SS Division Totenkopf machine-gunned 97 British and French prisoners near the La Bassée Canal. The British prisoners were from the 2nd Battalion, Royal Norfolk Regiment, part of the 4th Brigade of the 2nd Division. The SS men lined them up against the wall of a barn and shot them all; only two survived. Meanwhile, the Luftwaffe dropped bombs and leaflets on the Allied armies. The leaflets showed a map of the situation. They read, in English and French: "British soldiers! Look at the map: it gives your true situation! Your troops are entirely surrounded—stop fighting! Put down your arms!" To the land- and air-minded Germans, the sea seemed an impassable barrier, so they believed the Allies were surrounded; but the British saw the sea as a route to safety.
Besides the Luftwaffes bombs, German heavy artillery also fired high-explosive shells into Dunkirk. By this time, over 1,000 civilians in the town had been killed. This bombardment continued until the evacuation was over.
Battle of Wytschaete
Gort had sent Lieutenant General Ronald Adam, commanding III Corps, ahead to build the defensive perimeter around Dunkirk; his corps command passed to Lieutenant General Sydney Rigby Wason from the GHQ staff. Lieutenant General Alan Brooke, commanding II Corps, was to conduct a holding action with the 3rd, 4th, 5th, and 50th Divisions along the Ypres-Comines canal as far as Yser, while the rest of the BEF fell back. The battle of Wytschaete, over the border in Belgium, was the toughest action Brooke faced in this role.On 26 May, the Germans made a reconnaissance in force against the British position. At mid-day on 27 May, they launched a full-scale attack with three divisions south of Ypres. A confused battle followed, where visibility was low because of forested or urban terrain and communications were poor because the British at that time used no radios below battalion level and the telephone wires had been cut. The Germans used infiltration tactics to get among the British, who were beaten back.
The heaviest fighting was in the 5th Division's sector. Still on 27 May, Brooke ordered the 3rd Division commander, Major-General Bernard Montgomery, to extend his division's line to the left, thereby freeing the 10th and 11th Brigades, both of the 4th Division, to join the 5th Division at Messines Ridge. The 10th Brigade arrived first, to find the enemy had advanced so far they were closing on the British field artillery. Between them, the 10th and 11th Brigades cleared the ridge of Germans, and by 28 May they were securely dug in east of Wytschaete.
That day, Brooke ordered a counterattack. This was to be spearheaded by two battalions, the 3rd Grenadier Guards and 2nd North Staffordshire Regiment, both of Major-General Harold Alexander's 1st Division. The North Staffords advanced as far as the Leie River, while the Grenadiers reached the canal itself, but could not hold it. The counterattack disrupted the Germans, holding them back a little longer while the BEF retreated.
