On 21 May, the British launched an armored counterattack against the flanks of the 7th Panzer Division and SS-Totenkopf. The Germans then trapped the British and French troops in a huge pocket at Dunkirk. On 27 May, 4 Company, SS-Totenkopf perpetrated the Le Paradis massacre, where 97 men of the 2nd Battalion, Royal Norfolk Regiment were machine-gunned after surrendering, with survivors finished off with bayonets. Two men survived. By 28 May the SS-Leibstandarte had taken Wormhout, from Dunkirk. There, soldiers of the 2nd Battalion were responsible for the Wormhoudt massacre, where 80 British and French soldiers were murdered after they surrendered. According to historian Charles Sydnor, the "fanatical recklessness in the assault, suicidal defense against enemy attacks, and savage atrocities committed in the face of frustrated objectives" exhibited by the SS-Totenkopf division during the invasion were typical of the SS troops as a whole. At the close of the campaign, Hitler expressed his pleasure with the performance of the SS-Leibstandarte, telling them: "Henceforth it will be an honor for you, who bear my name, to lead every German attack."

Campaign in the Balkans In April 1941, the German Army invaded Yugoslavia and Greece. The LSSAH and Das Reich were attached to separate army Panzer corps. Fritz Klingenberg, a company commander in the Das Reich, led his men across Yugoslavia to the capital, Belgrade, where a small group in the vanguard accepted the surrender of the city on 13 April. A few days later Yugoslavia surrendered. SS police units immediately began taking hostages and carrying out reprisals, a practice that became common. In some cases, they were joined by the Wehrmacht. Similar to Poland, the war policies of the Nazis in the Balkans resulted in brutal occupation and racist mass murder. Serbia became the second country (after Estonia) declared Judenfrei (free of Jews). In Greece,
