They Were Great Generals and Christian Soldiers and Waged War Like Gentlemen.
-- Ferguson

According to

The funds for the sculpture came from J. Henry Ferguson, the banker who organized the Colonial Trust Company. In his will, he left specific instructions for a monument of his childhood heroes, Robert E. Lee and Stonewall Jackson, which was gifted to the City of Baltimore. Although Ferguson died in 1928, the sculpture was not dedicated until 1948 due to various factors, including World War II.
