…To state the question more directly, are all the laws, but one, to go unexecuted, and the government itself go to pieces, lest that one be violated?

A proclamation on the suspension of habeas corpus, 1862
When Abraham Lincoln took office in March 1861, the executive branch was small and relatively limited in its power. By the time of his assassination, he had claimed more prerogatives than any president before him, and the executive branch had grown enormously.
By December 1862, Congress was able to vote on an official suspension of habeas corpus. This time, Congress prevailed by passing the Habeas Corpus Suspension Act, signed into law March 3, 1863. This piece of legislation gave the president the power to officially suspend habeas corpus without the direct consent of Congress*. Lincoln had achieved a great strategic victory in attempting to suppress the rebellion. The suspension of the writ of habeas corpus was eventually terminated in December 1865 by President Andrew Johnson.

He was then compelled to rise from his bed, taken into custody, and conveyed to Fort McHenry, where he is imprisoned by the commanding officer, without warrant from any lawful authority.
On this day in 1861, in the second month of the Civil War, Union troops arrested John Merryman, a Maryland state legislator. He was indicted for treason and confined at Baltimore’s Fort McHenry, charged with seeking to hinder U.S. troop movements from Baltimore to Washington, which was threatened by Confederate forces.
