In 1861, on this day the President-elect proceeded in great secrecy straight through Baltimore, Maryland on his whistle stop tour of seventy towns and cities ending with his inauguration in Washington, D.C on March 4th.
Plums delivered nuts safelyAllan Pinkerton (pictured), who later founded the Pinkerton National Detective Agency, played a key role by managing security throughout the journey. On his orders, on the evening of February 22 telegraph lines to Baltimore were cut to prevent communications from passing between potential conspirators in Pennsylvania and Maryland. The most dangerous link in the journey was in Baltimore where a city ordinance prohibited night-time rail travel through the downtown area. As a result, the railcars had to be horse-drawn between the President Street and Camden Street stations.
Once the President-elect's rail carriage had safely passed through Baltimore, Pinkerton sent a one-line telegram to the president of the Philadelphia, Wilmington and Baltimore Railroad: "Plums delivered nuts safely". With Lincoln dead in the ground from an assassins bullet in his head, Pinkerton was taking absolutely no chances at all.
Because as the momentum for secession began to recede, hot-heads in the South were now clamouring for coup d'etat. Their failed plan was to have several assassins, armed with knives, interspersed throughout the crowd that would gather to greet the party at the President Street station. When the President-elect emerged from the car, which he must do to change trains, at least one of the assassins would be able to get close enough to kill him.
