From his youth, Milligan was active in partisan politics. As a young man, he took a prominent role in Belmont County Democratic Party affairs in defense of Jeffersonian states-rights positions. During the
Nullification Crisis of the early 1830s, he echoed South Carolinian John C. Calhoun's stance that the states could "nullify" offensive federal laws. He followed Calhoun into the Whig Party, but then followed Calhoun back to the Democratic Party when President Martin Van Buren wooed him back to the fold. Milligan continued to be active in Democratic Party affairs after his move to Indiana. Resuming his law practice after a hiatus of real estate speculation and holding county positions, he developed a solid reputation as a successful lawyer, mostly representing small railroad companies. Milligan also ran as a Democrat for political office, but consistently lost at the polls. In 1862 he failed to secure Indiana's Democratic nomination for a seat in Congress, and in 1864 he failed to get the Democratic nomination for
governor of Indiana. By the end of 1863 military authorities in Indianapolis believed that Milligan was involved in a conspiracy against the United States and sent army detectives to observe his actions.
Arrest and detention On September 17, 1864,
General Alvin Peterson Hovey, commander of the Military District of Indiana, authorized a military commission to meet on September 19 at
Indianapolis, Indiana, to begin trials of those placed under military arrest. Among them was Lambdin Milligan, who was arrested at his Huntington home on October 6, 1864. Two other men, James B. Wilson and David T. Yeakel, were also seized. Because President Lincoln had suspended the
writ of
habeas corpus on September 24, 1862, as authorized under Article 1 of the
U.S. Constitution, and
Congress ratified this action on March 3, 1863, with the passage of the
Habeas Corpus Suspension Act, no warrant or affidavit was issued to show justification for Milligan's arrest. Dodd escaped from jail during his trial and fled to
Canada. He was found guilty in absentia on October 10, 1864, and sentenced to hang. Charges against Bingham, Heffren, Harrison, Yeakel, and Wilson were dismissed with deals to be witnesses for the military prosecution.
Trial and conviction The
military tribunal for the trial of Milligan, Bowles, Horsey, and Humphreys convened at Indianapolis on October 21, 1864. The commission considered five charges: •
Conspiracy against the U.S. government • Offering aid and comfort to the
Confederates • Inciting
insurrections • Disloyal practices • Violation of the
laws of war The defendants were accused of establishing a secret organization that planned to liberate Confederate prisoners from Union
prisoner-of-war camps in
Illinois, Indiana, and Ohio; steal weapons from an arsenal; raise an armed force to incite a general insurrection; and join with the Confederates to invade Indiana, Illinois, and
Kentucky and make war on the U.S. government. Democrats charged that the arrests and trials by military commission were politically motivated amid a climate of bitter political disputes between Democrats and Republicans about the conduct of the war. Scholars who have studied the trials believe the adjutant general did not adequately prove that Milligan was guilty of the charges made against him. In addition, they suggest that the trials, which were highly publicized in the press, were prompted by partisan politics, convened before commission of biased military officers, failed to follow the rules of evidence, and used questionable informers as witnesses. The
Indianapolis Daily Sentinel, which supported the Democrats, blamed Governor Morton, a Republican, for the arrest and detention of its editor, Bingham, and called on the state's voters to oppose Morton's re-election in 1864. During the trials, members of the military commissions made speeches at Republican rallies. The controversial proceedings led to the landmark U.S. Supreme Court case known as
Ex parte Milligan. On December 10, 1864, Milligan, Bowles, and Horsey were found guilty on all charges and sentenced to hang on May 19, 1865. Humphreys was found guilty and sentenced to hard labor for the remainder of the war, but his sentence was later modified, allowing his release. Efforts were made to secure pardons for Milligan, Bowles, and Horsey, with the decision passing to President
Andrew Johnson following
Lincoln's assassination. On May 16 the executions of Milligan and Bowles were postponed to June 2, and Horsey's sentence was commuted to life imprisonment. President Johnson approved commutation of the sentences for Milligan and Bowles to life imprisonment on May 30, 1865. The prisoners were transferred from Indianapolis to a federal prison at
Columbus, Ohio.
Circuit Court appeal On May 10, 1865, Jonathan W. Gordon, Milligan's legal counsel, filed a
petition in the U.S. Circuit Court for the District of Indiana at Indianapolis for a writ of
habeas corpus, which called for a justification of Milligan's arrest. Justice
David Davis, an
associate justice of the U.S. Supreme Court and a federal circuit court judge, and Judge Thomas Drummond, another federal circuit court judge, reviewed Milligan's appeal, which claimed he should not have been tried by a military commission. The two judges disagreed over the issue of whether the U.S. Constitution prohibited civilians from being tried by a military commission and passed the case to the
U.S. Supreme Court. ==
