During the 1870s there was an economic depression called the "Panic of 1873." After the Panic, the Baltimore & Ohio Railroad company decided to pay its workers less. This caused the Great Railroad Strike of 1877. These strikes stopped train service in Cumberland in western Maryland. On July 20, 1877, the Maryland Governor, John Lee Carroll, ordered the Maryland Army National Guard to stop the strikes. People who supported the railroad workers attacked the national guard soldiers. Soldiers from the 6th Regiment fired their guns at the crowd. 10 people were killed, and 25 people were hurt. This started a riot. Trains were damaged and parts of Camden Station were burned. US Army soldiers came to Baltimore to protect the railroad and end the strike. The riot and strike ended on July 21–22, 1877.
