Led by Lt. Colonel Joshua Chamberlain, the 20th Maine played a decisive role in the Union victory
at Gettysburg. Running low on supplies and ammunition, the 20th held its position on Little Round
Top, preventing the Confederates from flanking the Union line.
When the smoke cleared, 29 of the 20th Maine's 386 men were killed, 91 wounded, and 5 missing.
Chamberlain and Sgt. Andrew Tosier received the Medal of Honor for their actions defending Little
Round Top on July 2, 1863.

On the morning of July 1, 1863, the quiet town of Gettysburg, PA, became the focal point of one of the greatest battles of the American Civil War as Robert E. Lee's Confederate Army of Northern Virginia clashed with George G. Meade's Union Army of the Potomac. The ensuing 3-day battle would become the bloodiest in U.S. history as the Union sought to block the Confederate's invasion of northern territory.
Following his victory at the Battle of Chancellorsville, Robert E. Lee ordered his army to move north into Union territory. By late June, elements of the Army of Northern Virginia had crossed the Mason-Dixon Line (the boundary separating the "North" and "South") and were reconnoitering the area of Gettysburg, York, and Harrisburg, PA.
Upon entering Gettysburg on June 30 in search of supplies, Confederate troops under General Henry Heth were surprised to find Union cavalry defending the town. The next day, Heth ordered his division to engage the Union cavalry. The cavalrymen delayed the Confederates long enough for reinforcements to arrive. As the day wore on, more and more troops were thrown into the engagement. Fierce fighting eventually overwhelmed the Union lines and pushed them south of the town by day's end.
Overnight, the Armies of the Potomac and Northern Virginia—approximately 175,000 troops—converged on Gettysburg. On July 2, Lee hoped to capitalize on the previous day's success by ordering Generals James Longstreet and Richard Ewell to attack the Union flanks. Despite suffering heavy losses, the Union's strong defensive position, heroic resistance, and Meade's skillful movement of reinforcements prevented Lee from striking the decisive blow on northern territory that he desired.
Unable to dislodge the Union on the left and right, Lee believed victory would be achieved with an assault on the Union's center at Cemetery Ridge on July 3. That afternoon, the general ordered a massive artillery bombardment followed by a 15,000-man assault. General George Pickett led the Confederate charge across nearly three-quarters of a mile of open fields. As they advanced, withering musket and cannon fire from the front and sides ripped through the Confederate ranks. Although small groups of Confederates penetrated the Union line, reinforcements quickly captured, killed, or forced the rebels to retreat. By sunset of the third day, less than half the men who participated in Pickett's Charge returned to the Confederate lines.
That evening, the Army of Northern Virginia moved to defensive positions in anticipation of a Union counterattack that never materialized. They retreated to Virginia on July 4. Approximately 51,000 (28,000 Confederate and 23,000 Union) soldiers were dead, wounded, or missing. One civilian died as a result of the battle—Mary "Ginnie" Wade was killed by a stray bullet as she kneaded dough in her sister's house.
Four months after the battle, President Abraham Lincoln arrived in Gettysburg to dedicate the Soldiers' National Cemetery. During the ceremony, Lincoln's Gettysburg Address defined the war as not only a struggle to preserve the Union, but also for the principle of human equality.
Leading a demoralized army and facing criticism of his actions in southern newspapers, Lee offered his resignation to President Jefferson Davis. Davis refused. Lee and the Army of Northern Virginia would continue fighting until their surrender at Appomattox Courthouse on April 9, 1865.
You can learn more about the American Civil War and its combatants using census data and records. For example:
Winfield Scott Hancock (center, right of tree) distinguished himself during the Battle of Gettysburg along Cemetery Ridge where he bore the brunt of Pickett's Charge
and was wounded, but refused evacuation until hostilities ended.
The next year, Hancock was at Ream's Station, outside of Petersburg, VA, with future superintendent of the census Francis Amasa Walker (far right). Confederates
captured Walker on August 25, 1864, as he carried orders from Hancock to Generals John Gibbon and Nelson A. Miles.

On July 10, 1820, J.D.B. DeBow, who headed the Census Office from 1853–1857, was born in Charleston, SC.
DeBow oversaw the tabulation and publication of the 1850 Census. Included in these publications was the Statistical View of the United States. It featured the "DeBow Map"—the first map in a census publication.
President Abraham Lincoln was possibly suffering from the early stages of smallpox when he attended (above) the November 19, 1863, dedication of the Soldiers' National Cemetery in Gettysburg, PA.
He was quite ill one week later, but recovered sufficiently to attend a play at Ford's Theater on December 6. His personal valet, William H. Johnson, was not so lucky. After tending the president during his illness, Johnson died from the disease in January 1864.
In 1860, smallpox claimed the lives of 1,263. Ten years later, the census reported that, thanks to vaccination efforts, the disease killed 4,507. In 1980, the World Health Assembly reported that naturally occurring smallpox had been eradicated worldwide.

Francis Amasa Walker oversaw the 1870 and 1880 Censuses. He was wounded during the May 1863 Battle of Chancellorsville and captured during the 1864 Siege of Petersburg, VA.
Seaton Device inventor Charles W. Seaton (pictured above) led the Census Office from 1881 to 1885. He served in the 1st U.S. Sharpshooters from August 1861 to May 1863, and was wounded during the 1862 Battle of Malvern Hill.
Carroll D. Wright was superintendent of the census from 1893 to 1897. In 1862, he enlisted in the 14th New Hampshire Volunteer Regiment. By the 1864 Shenandoah Campaign, he was assistant adjutant general to General Philip Sheridan.
