Query: In what year did the French reach Alsace?
Context: During the next century, France was to be militarily shattered by the Hundred Years' War, which prevented for a time any further tendencies in this direction. After the conclusion of the war, France was again free to pursue its desire to reach the Rhine and in 1444 a French army appeared in Lorraine and Alsace. It took up winter quarters, demanded the submission of Metz and Strasbourg and launched an attack on Basel.
