On 6 June 1944, American, British, and Canadian forces established a front in France with the D-Day landings in Normandy.[140] On 20 July 1944, Hitler survived an assassination attempt.[141] He ordered brutal reprisals, resulting in 7,000 arrests and the execution of more than 4,900 people.[142] The failed Ardennes Offensive (16 December 1944 – 25 January 1945) was the last major German offensive on the western front, and Soviet forces entered Germany on 27 January.[143] Hitler's refusal to admit defeat and his insistence that the war be fought to the last man led to unnecessary death and destruction in the war's closing months.[144] Through his Justice Minister Otto Georg Thierack, Hitler ordered that anyone who was not prepared to fight should be court-martialed, and thousands of people were put to death.[145] In many areas, people surrendered to the approaching Allies in spite of exhortations of local leaders to continue to fight.
