It surrounded the capital.
Abraham Lincoln
Lincoln was threatened by Maryland dues to its close proximity to Washington DC. He suspended Habeas Corpus in Maryland, which meant he could punish people without evidence, basically infringing upon the 4th amendment. He would have marylanders arrested for so much as speaking a word against the Union. For a historical parallel, look up the alien and sedition acts created by john Adams in the late 1700s.
Lincoln assured the border states that he would take no action to deprive them of their slaves. He declared martial law in Maryland, and sent troops to prevent Maryland from seceding, because if its close proximity to Washington, D.C. He also sent troops to Kentucky after the Confederates violated Kentucky's declared neutrality. The Missouri Federal Militia was able to drive out the Missouri Confederate Militia in fairly short order; so Lincoln appointed Missourian Halleck to replace Scott as the General-in-Chief of the Army until Grant replaced him in 1864.
The Border States were the slave-states of the Upper South which narrowly voted against joining the Confederacy. They were Missouri, Kentucky, Maryland and Delaware. Maryland was especially important, because if it had seceded, Washington D.C. would have been totally surrounded by enemy states.To prevent this, Lincon had to break the law by jailing some of their pro-Southern leaders without trial.
To prevent the South from exchanging its cotton for military material from abroad.
False.
Abraham Lincoln
To prevent the south from seceding from the north.
Washington, DC straddles the border between Maryland and Virginia. With Virginia already part of the Confederacy, if the Union lost Maryland, DC would have been cut off completely and captured by the Rebels.
Abraham Lincoln suspended Habeas Corpus at the beginning of the Civil War. Since Maryland was a border state and close to Washington, DC, authorities would have able to arrest anyone who attempted to cause the state to secede from the Union. Lincoln sent Federal troops to Maryland. He made it clear that Maryland should not leave the Union. Although there were many people in Maryland who wanted to join the South, there was not enough to bring the state into the Confederacy.

Lincoln was worried about Maryland seceding due to the close proximity to Washington, DC. To prevent Maryland from seceding he suspended Habeas Corpus in Maryland. This allowed him to arrest Maryland residents without giving any reason or explanation. If they dared talk of seceding they could be imprisoned.
President Lincoln stated that in his view, secession was unconstitutional. He vowed to protect Federal property and added he would enforce the Fugitive Slave Act. Lincoln did all he could to prevent and bring back to the Union secessionist states.
So that he could keep some of its pro-Southern leaders in jail, and prevent the state from voting Confederate.
Just prior to the outbreak of the American Civil War, President James Buchanan did not use force to try to prevent the Southern states from seceding from the Union. Believing secession to be illegal, but also believing that the Federal government had no right to use force to prevent secession, President Buchanan alienated both Southerners and Northerners in his final months in office before Abraham Lincoln was sworn in (in March 1865) as the country's next president.
