deny—though Isaac R. Trimble, commanding Baltimore militia companies immediately following the Riot—later claimed that Brown authorized destruction of the railroad bridges, which may explain Brown's later arrest and imprisonment by federal authorities. Shortly thereafter, a Maryland militia captain and Baltimore County farmer, John Merryman, was arrested, held at Fort McHenry and later denied a writ of habeas corpus, on grounds that President Lincoln had suspended the writ (but only along rail lines in Maryland). This arrest sparked the case of Ex parte Merryman. President Lincoln agreed to reroute Union troops around Baltimore to Annapolis, so they could then travel to Washington. Northern troops (state militia companies) were able to arrive in Washington, thus avoiding further bloodshed in Baltimore. Imprisonment On May 13, 1861, the Union army entered Baltimore, occupied the city, and declared martial law. Mayor Brown was arrested on September 12, 1861 at his home. He was imprisoned at Fort McHenry for one night, then transported to Fort Monroe in Hampton Roads, Virginia, and held for two weeks. Afterwards he was moved to Fort Warren in Boston Harbor and held for fourteen months. Brown was released on November 27, 1862. He returned to Baltimore and resumed his law practice. Francis Key Howard, the grandson of Francis Scott Key, was also made a prisoner. Later life While speaking at St. John's College in Annapolis, MD, in 1869, Brown made reference to “A great university hereafter to be established in Baltimore … planned … by the wealthiest of her citizens, a native of this county [ Anne Arundel County ].” While Brown did not name the individual, he was referring to Johns Hopkins, who in 1867 had announced his intention to found a university and a hospital upon his death. Brown and Hopkins were contemporaries and respected each other, so it was not surprising that Brown should be named one of the twelve original trustees of the Johns Hopkins University. After Hopkins’ death on December 24, 1873, and the settling of his estate, the trustees began in earnest to plan the new university. While it was Daniel Coit Gilman’s idea to found the first research university in the United States, based on the German model, Brown heartily supported the idea. Brown also took part in debates over how much of the old classical curriculum should be preserved in the new scheme. Should Greek and Latin be replaced by modern languages? Should
