The following day, with the assistance of further artillery, Stuka dive bomber strikes, the 218th was able to pierce the French defenses, together with 21st and 239th infantry divisions. By 19 June, the division had advanced a further 15 miles into the Vosges Mountains. The French Army was in a state of collapse, as on the previous day, Guderian's Panzer forces had reached the Swiss border, effectively surrounding the French defenders in the Vosges and 3 days later the armistice was signed at Compiègne, marking the end of hostilities.
