Months after the incident, while serving as an officer on the staff of General Ulysses S. Grant, Robert Lincoln recalled the incident to his fellow officer, Colonel Adam Badeau, who happened to be a friend of Edwin Booth. Badeau sent a letter to Booth, complimenting the actor for his heroism. Before receiving the letter, Booth had been unaware that the man whose life he had saved on the train platform had been the president's son. The incident was said to have been of some comfort to Edwin Booth following his brother's assassination of the president. President Ulysses S. Grant also sent Booth a letter of gratitude for his action.
