From June 29 to July 6, 1913, the Union and Confederate flags flew side by side when more than 50,000 Civil War veterans convened in Gettysburg, Pennsylvania, to commemorate the 50th anniversary of one of the most pivotal battles in American history. Here’s a closer look at the Great Reunion of 1913.

The Idea

In April 1908, General H. S. Huidekoper, a Philadelphia native who lost his right arm at Gettysburg in 1863, suggested a fitting semicentennial observance of the three-day battle to Pennsylvania Governor Edwin S. Stuart.

Stuart, who presented the idea to the state’s General Assembly in January 1909 and established the Fiftieth Anniversary of the Battle of Gettysburg Commission later that year, envisioned a reunion of Union and Confederate soldiers that would be talked about for years to come. “Other States, both north and south, whose sons fought at Gettysburg, will surely co-operate in making the occasion one that will stand foremost in the martial history of the world,” he said.

Several reunions had been held at Gettysburg before, including one to commemorate the 15th anniversary, but this one would trump them all.

The Planning

John K. Tener, a former major league baseball player who succeeded Stuart as Pennsylvania Governor in 1911, oversaw most of the planning for the reunion. Invitations were extended to all Civil War veterans and the Commission called upon the National Government and individual states to appropriate funds for travel to and from Gettysburg, predominantly by rail.

With assistance from the War Department, the Commission helped prepare Gettysburg, a town of 4,500, for the 100,000 visitors (about half of them non-veterans) expected to attend the reunion. The official celebration would be held from July 1 (Veteran’s Day) to July 4.

The Great Camp

The camp for the veterans at Gettysburg officially opened on June 29, and the first meal of the reunion was served that evening. About 25,000 veterans, including Major Gen. Daniel E. Sickles, the only surviving corps commander on either side, arrived on the first day.

The camp comprised 280 acres and more than 5,000 tents, which were organized by state and equipped with two hand basins and a water bucket. Artesian wells were installed in the months leading up to the reunion to supply water to the veterans’ village. According to the Commission’s report, there were 53,407 veterans in camp. In addition, 124 officers and 1,342 enlisted men were assigned by the War Department to help make sure things ran smoothly, while 155 newspapermen and 2,170 cooks brought the total in camp to 57,198.

Only veterans with the proper credentials, such as honorable discharge or pension papers, were fed and sheltered in the camp. Most of the 50,000 non-veterans who traveled to Gettysburg to share in the celebration were housed at Gettysburg College.

Exercises in the Great Tent

Public exercises were held July 1-4 in a giant tent, equipped with 13,000 chairs, inside the camp. Colonel J.M. Schoonmaker, the chairman of the Pennsylvania Commission, opened the ceremonies on July 1 at 2 p.m. Dedications of state monuments followed. The second day of the reunion, Military Day, featured a reading of Abraham Lincoln’s Gettysburg Address and the introduction of members of Union Gen. George G. Meade’s family. July 3, Governor’s Day, featured 65 regimental reunions, speeches by more than a dozen Governors, a flag ceremony at the site of Pickett’s charge, and a fireworks display. An address by President Woodrow Wilson highlighted the festivities on the Fourth of July.

Sweltering Conditions

Temperatures climbed into the triple digits on the first few days of the reunion. According to a report by the U.S. Army’s Chief Surgeon, 744 cases were admitted to the camp’s hospitals, and 319 of those were for heat exhaustion. (Sunstroke and tonsillitis each accounted for one case.) There were nine fatalities during the reunion, but considering the mean age of the veterans present was 72 and that most had traveled hundreds of miles to attend, it’s a wonder that number wasn’t greater. The post-reunion report by the Pennsylvania Commission declared the number of fatalities as “nothing short of marvelous.”

Food and Supplies

Cooks served 688,000 meals from June 29 to July 6. The great camp was stocked with 156,410 pounds of meat, 14,722 pounds of fowl, 7,008 cans of fish, 24,930 dozen eggs, 12,383 pounds of butter, and 403 gallons of pickles, among many other provisions. The dessert menu included 2,015 gallons of ice cream and 7,000 pies. Unused meat and vegetables were sold at auction after the camp closed. Fifty-four thousand mess kits were provided to the veterans as souvenirs. Each mess kit contained a fork, knife, small and large spoon, tin cup, and two plates. Veterans were asked to bring their own towels and toiletries.

Reunions Within the Reunion

When they weren’t taking in the scheduled public exercises at the reunion, veterans spent their time in Gettysburg reminiscing with friends and getting to know former foes. It was common for a veteran to seek out a man who may have shot him or exchange badges with a soldier from the other side. Two men reportedly purchased a hatchet at a local hardware store, walked it to the site where their regiments fought, and buried it. Here are three of the more interesting mini-reunions mentioned in the Pennsylvania Commission’s report and various newspaper accounts:

Flower Girls

When Gen. John Buford’s blue-uniformed soldiers rode through the streets of Gettysburg on June 30, 1863, a throng of girls in white dresses greeted them. The girls sang patriotic songs and threw flowers while standing on grocery boxes to get a better look at the troops. “It was a mighty cheering preparation for the fight of the next day,” one member of the Sixth New York Cavalry recalled. Fifty years later, the members of the Sixth New York Cavalry who returned to Gettysburg combed the town in search of surviving members of that welcoming party. They found six women, who were brought to camp for an impromptu reunion. “We wish to thank you and say ‘God bless you’ for the friendly greeting you extended to us in those days so long ago, when kind words from gentle and noble women were like an oasis in a desert,” one member of the Sixth said. The women then sang a stirring rendition of “Rally Round the Flag.” Bragging Rights

An op-ed in The New York Times during the reunion mentioned that many veterans reminisced about their experiences at Gettysburg in 1863 as they would a baseball contest. A separate article described the scene of a Union and a Confederate soldier posing for a photo by shaking hands next to a cannon. The Union soldier turned to the Confederate and said, “I’m mighty glad to do this, you know; but still, you know, we did lick you.” “You Are the Man”

Yet another New York Times article detailed an encounter between a Confederate soldier who was shot at the Bloody Angle, and would have died, were it not for a Union soldier who came to his rescue. A Union soldier who heard this story told the Confederate that he had saved a Confederate at the Bloody Angle that day, describing exactly what he had done. The Confederate examined the Union soldier more closely and declared, “But my God, that’s just what the Yankee did for me. There couldn’t have been two cases like that at the same time. You are the man.”

President Wilson’s Address

President Wilson initially declined the invitation to the reunion, having established a personal rule not to leave Washington for any speechmaking occasion while Congress was in session, but he ultimately reconsidered and decided to attend. Wilson addressed the camp at 11 a.m. on the Fourth of July and left after the playing of the National Anthem. The process of shutting down the camp began soon after. The hospital closed on July 5, fewer than 300 veterans remained on the night of July 6, and the last veteran left on July 8.

1938 Reunion

A 75th anniversary reunion was held in 1938, but as you might imagine, most Civil War veterans had passed away by then. About 25 veterans who had fought at Gettysburg and 2,000 other veterans attended.
