  • French and German representatives met to negotiate peace at the 1918 Armistice site at Compiègne, France, using the very same rail carriage where the WW1 armistice, brought from a French museum, for the negotiations. Hitler personally attended the negotiation, but at 1530 hours abruptly left the meeting to show disrespect for the French. At 2030 hours, French General Huntzinger called his government and informed that the Germans allowed no room for negotiations and demanded harsh terms; he was told to accept the German terms. Meanwhile, in southern France, the 32 Italian divisions deployed on the French border marched through the Little Saint Bernard Pass in the Alps and along the French Riviera; some of the Italians were met with a heavy snow storm and the latter halted by a very small group of French troops at Menton, which was about 5 miles from the border. According to the diary of Galeazzo Ciano, Benito Mussolini was extremely embarrassed by the inability of his troops to break through the French lines. ww2dbase [Main Article | CPC]
