Prussia declares war on the German states of Hanover, Saxony, and Hesse.

As Prussia and Austria drifted towards war, Prussia offered the German states of Hanover, Saxony, and Hesse-Kassel, all considered as potential allies of Austria, membership in the new Prussian-led German Confederation.  All three refused and all three were invaded the following day.  Saxony and Hesse were occupied without resistance and although Hanover fought back, and despite a Hanoverian victory at Langensalza on June 27, 1866, its army was forced to surrender. This saw the end of the kingdom as a seperate state. (By John Osborne)
