History for the day: 18 November 1863: Lincoln travels to Gettysburg

History.com has this article for 18 November:

On 18 November 1863, President Abraham Lincoln boarded a train for Gettysburg, Pennsylvania, to deliver a short speech at the dedication of a cemetery of soldiers killed during the battle there on 1 July to 3 July 1863. The address Lincoln gave in Gettysburg became one of the most famous speeches in American history.
Lincoln had given much thought to what he wanted to say at Gettysburg, but nearly missed the chance to say it. Shortly before the trip his son, Tad, became ill with a fever. The president and his wife Mary Todd Lincoln were no strangers to juvenile illness: they had already lost two sons to disease. Prone to fits of hysteria, Mary Lincoln panicked as her husband prepared to leave. However, Lincoln felt the opportunity to speak at Gettysburg and present his defense of the war was too important to miss, so he boarded a train and headed to Pennsylvania.
Despite his son’s illness, Lincoln was in good spirits during the journey. He was accompanied by an entourage that included Secretary of State William Seward, Postmaster General Montgomery Blair, Interior Secretary John Usher, Lincoln’s personal secretaries John Hay and John Nicolay, several members of the diplomat corps, some foreign visitors, a Marine band, and a military escort.
When Lincoln arrived in Gettysburg, he was handed a telegram that lifted his spirits: Tad was much better. Lincoln enjoyed an evening dinner and a serenade by the Fifth New York Artillery Band before he retired to finalize his famous Gettysburg Address.
