In February, 1861, Abraham Lincoln transferred from the President Street station, to the Camden Station on his way to Washington, D.C. to be inaugurated as President of the United States. News of the Battle of Fort Sumter, beginning the Civil War, first reached Baltimore on April 12, 1861, at the B&amp;O's Camden Station telegraph office. The following week, Union troops of the 6th Massachusetts Militia travelling south on the B&amp;O barricaded themselves at Camden Station when they were attacked by Confederate sympathizers in the Baltimore riot of 1861. During the four-year conflict, the B&amp;O's line between Baltimore and Washington, D.C. was the sole rail link between the Federal capitol and the North, resulting in a vital role for Camden Station as B&amp;O's Baltimore terminal. Trainloads of wounded soldiers and Confederate POWs came through the station following the Battle of Antietam,  west of Baltimore on September 17, 1862. President Lincoln changed trains at Camden Station on November 18, 1863 en route to Gettysburg, Pennsylvania to deliver the Gettysburg Address. Lincoln also used Camden Station on April 18, 1864 when he made an overnight visit to Baltimore for a speaking engagement. A year later, at 10 a.m. on April 21, 1865, the assassinated president's nine-car funeral train arrived at Camden Station, the first stop on its slow journey from Washington to Springfield, Illinois, via the B&amp;O and the Northern Central Railway's Baltimore-Harrisburg, Pennsylvania, line.
