afraid the fire would spread to their neighboring houses. Cockburn wanted to destroy the newspaper because its reporters had written so negatively about him, branding him "The Ruffian". Instead, he ordered his troops to tear the building down brick by brick, and ordered all the "C" type destroyed "so that the rascals can have no further means of abusing my name". The British sought out the United States Treasury in hopes of finding money or items of worth, but they found only old records. They burned the United States Treasury and other public buildings. The United States Department of War building was also burned. However, the War and State Department files had been removed, so the books and records had been saved; the only records of the War Department lost were recommendations of appointments for the Army and letters received from seven years earlier.
