The War begins

In response to Austria’s declaration of war, Russia, Serbia’s ally, began moving its army toward the Russian-Austrian border and along the German border. To Germany, this Russian mobilization amounted to a declaration of war. On August 1, the German government declared war on Russia. Russia looked to its ally France for help. Germany, however, did not even wait for France to react. Two days after declaring war on Russia, Germany also declared war on France. Soon afterward, Great Britain declared war on Germany.
