June 18, 1812 – After much debate, the U.S. Senate voted 19 to 13 in favor of a declaration of war against Great Britain, prompted by Britain’s violation of America’s rights on the high seas and British incitement of Indian warfare on the Western frontier. The next day, President James Madison officially proclaimed the U.S. to be in a state of war. The War of 1812 lasted over two years and ended with the signing of the Treaty of Ghent in Belgium on December 24, 1814.

June 18, 1815 – On the fields near Waterloo in central Belgium, 72,000 French troops, led by Napoleon, suffered a crushing military defeat from a combined Allied army of 113,000 British, Dutch, Belgian, and Prussian troops. Thus ended 23 years of warfare between France and the other powers of Europe. Napoleon was then sent into exile on the island of St. Helena off the coast of Africa. On May 5, 1821, the former vain-glorious Emperor died alone on the tiny island, abandoned by everyone.

Birthday – British explorer George Mallory (1886-1924) was born in Mobberley, Cheshire, England. When asked why he wanted to climb Mount Everest, the highest mountain in the world, he simply answered, “Because it is there.” He disappeared while climbing through the mists toward its summit on the morning of June 8, 1924. His body, perfectly preserved due to the cold conditions, was discovered by climbers in 1999, just 600 meters (2,030 feet) from the summit.
