The elected state leaders of Maryland would have left the Union, but the Federal government put them all in prison before they had a chance, and kept them there, without charges, and suspended the Constitutional Right of Habeus Corpus, so they could not petition for their release.

Missouri likewise would have left the Union, but prompt action by a US Army officer on the scene, Nathaniel Lyon, assisted by pro-Union militia groups of German immigrants, prevented it. Kentucky at first declared "neutrality". Military commanders on both sides outside Kentucky coveted strategic locations along the Ohio River in northern Kentucky, and the Confederates acted first, "invading" Kentucky to seize the high ground at Columbus. This forced Kentucky into the Union camp. Kentucky, Maryland and Missouri sent men to the armies of both sides, though.
