What happened June 1862 AD

In June 1862, he sailed from Genoa and landed again at Palermo, where he gathered volunteers for the campaign, under the slogan o Roma o Morte. The garrison of Messina, loyal to the king's instructions, barred their passage to the mainland. Garibaldi's force, now numbering two thousand, turned south and set sail from Catania.

McClellan then resisted the president's demand that he pursue Lee's withdrawing army, while General Don Carlos Buell likewise refused orders to move the Army of the Ohio against rebel forces in eastern Tennessee. Lincoln replaced Buell with William Rosecrans; and after the 1862 midterm elections he replaced McClellan with Ambrose Burnside. The appointments were both politically neutral and adroit on Lincoln's part.

In June 1862, Congress passed an act banning slavery on all federal territory, which Lincoln signed.
