Let’s Begin…

Geographer Anne Knowles uses digital technologies to reimagine the past. In this fascinating talk, Knowles transports us to the Battle of Gettysburg, the turning point of the Civil War. Using Geographic Information Systems (GIS) and historical maps, she traces the footsteps of Robert E. Lee as he orders Pickett’s Charge -- and makes an educated guess why he made this crucial mistake.

Memorial Day is a US federal holiday wherein the men and women who died while serving in the United States Armed Forces are remembered.The holiday, which is celebrated every year on the final Monday of May, was formerly known as Decoration Day and originated after the American Civil War to commemorate the Union and Confederate soldiers who died in the Civil War. By the 20th century, Memorial Day had been extended to honor all Americans who have died while in the military service. It typically marks the start of the summer vacation season, while Labor Day marks its end.The muffled drum's sad roll has beat The soldier's last tattoo; No more on Life's parade shall meet That brave and fallen few. On Fame's eternal camping-ground 5 Their silent tents are spread, And Glory guards, with solemn round, The bivouac of the dead. Bivouac Of The Dead, by Theodore O'Hara.This site was created in 1994 to be a central point of information about Memorial Day in the United States of America, help restore its original intent, and to provide others a chance to share their feelings, pride, respect, and honor for those that gave their all.The Civil War, which had torn our nation apart, had come to an end. In Waterloo, NY, as in the rest of the nation, the great sacrifice of our most precious asset, our young men, weighed heavily on the minds of our citizens. During the fall of 1865, Henry C. Wells, a local Druggist, proposed that a commemoration be held to honor their sacrifice. Late in the winter of 1866, he enlisted the aid of General John B. Murray who immediately threw his support behind the proposal and on May 5, 1866 the first Memorial Day was held.Memorial Day, an American holiday observed on the last Monday of May, honors men and women who died while serving in the U.S. military. Originally known as Decoration Day, it originated in the years following the Civil War and became an official federal holiday in 1971. Many Americans observe Memorial Day by visiting cemeteries or memorials, holding family gatherings and participating in parades. Unofficially, at least, it marks the beginning of summer. See a History Channel video here.The Battle of Gettysburg was fought July 1–3, 1863, in and around the town of Gettysburg, Pennsylvania between Union and Confederate forces during the American Civil War. The battle involved the largest number of casualties of the entire war and is often described as the war's turning point.Speaking of maps, how are they made? Aris Venetikidis talks about how maps in the real world are often different than maps we make up in our brains.This animated map of the Battle of Gettysburg is really well done. Check it out here.Pickett's Charge was an infantry assault ordered by Confederate Gen.Robert E. Lee against Maj. Gen.George G. Meade's Unionpositions on Cemetery Ridge on July 3, 1863, the last day of the Battle of Gettysburg during the American Civil War. Its futility was predicted by the charge's commander, Lt. Gen. James Longstreet, and it was arguably an avoidable mistake from which the Southernwar effort never fully recovered psychologically. The farthest point reached by the attack has been referred to as the high-water mark of the Confederacy.

It is important because so we can learn from the past, make changes in the present, and prepare for the future so we don't make the same mistakes from the past and can learn from them.

As we continuously learn more about history it gives us a more informed point of view. At the same time, we can't ever get comfortable with an interpretation.
