March 3rd saw the appointment of Andrew Johnson as the
Military Governor of Tennessee by President Lincoln.
On that same day, the action in south Missouri continues as
Union General John Pope lays siege to New Madrid.
On the 4th, faulty communications resulted in the
relieving of General Grant from command by General Henry Halleck.
The Battle of Pea Ridge, also known as Elkhorn Tavern, was
fought from March 6-8 in northwest Arkansas near the Missouri border. Union forces under Samuel Curtis had driven Confederates
from central Missouri into northwest Arkansas.
Confederate General Earl Van Dorn launched a counter-offensive but
Curtis held off the attack and drove the southerners from the battlefield on
the second day. It was one of the few
battles in the entire war when the Confederates had a numerical superiority on
the battlefield. It was a costly fight
for the south. Three CSA generals were
killed or mortally wounded and recent estimates put the overall loss at around
2,000 soldiers. After the battle, Van
Dorn’s forces were forced to live off the land for a week. During that time, thousands of troops
originally under Sterling Price deserted and returned home to Missouri. A few weeks later, the remnants of Van Dorn’s
forces were transferred to Tennessee, leaving Arkansas virtually undefended.
Also on March 6th, President Lincoln proposed
that slaves in border states be emancipated gradually with compensation being
paid to their owners. Also on that day,
the first Union ironclad ship, the USS Monitor put to sea from New York. And on the 8th the Confederate
Ironclad, CSS Virginia (also known as the Merrimac) engaged and destroyed two
Union frigates.
On March 8th, after intelligence reports of
increased Union activity provided by JEB Stuart, Joseph E. Johnston withdrew
the Confederate Army of the Potomac from Centerville, VA to the Rappahannock
River. On that same day, Lincoln,
frustrated at McClellan’s failure or refusal to appoint corps commanders, named
Edwin Sumner, Samuel Heintzelman, Erasmus Keyes, and Irvin McDowell to those
posts.
March 9th was an important date in Naval history
when the two opposing ironclads, Monitor and Merrimac faced off in Hampton
Roads, Virginia. The CSS Merrimac was
sent to the area in an attempt to break the Union blockade that was preventing
international shipments from reaching Norfolk and Richmond. The two ships fought for three hours, without
a decisive victory. However since
Merrimac retired to repair battle damage and the blockade remained intact, the
battle was clearly a strategic victory for the Union. Neither ship would survive the year. In May, after General Benjamin Huger
abandoned Norfolk without telling anybody in the Navy, the Merrimac was
stranded by low tide. Her Captain had
her burned. The ship’s magazine blew and
destroyed the ship. The Union Monitor
survived to the end of the year, when she foundered in high seas off the
Virginia Capes.
