Major Anderson's unprovoked, and unauthorized retreat into Fort Sumter sure seems to be one. Upgrading the defences of Fort Moultrie from the land side, planting explosives meant to kill large numbers of people. Aiming loaded and primed artillery pieces at civilian shipping. Burning and destroying government property before secretly moving his command from Fort Moultrie to the unfinished Fort Sumter- against the agreements between South Carolina and the President. Capturing and holding against their will, at the point of bayonet, civilian workers within Fort Sumter. All before the first shot.
Then with after all of this, after wrapping himself with the flag, refused to defend that flag when it was fired upon, a duty as a commissioned officer he was sworn to do, when the Star of the West tried to reenforce his command.
Anderson's acts were unsound and unstable but protected by his government.
Lincoln could have ended the stalemate peacefully but he chose war instead. His intent was to provoke the South into firing the first shot, if not that, at least capturing the most important military asset, Fort Pickens.
