Do you know what happened on March 21 during the U.S. Civil War?

In 1861 Confederate Vice President Alexander Stephens enumerated contrasts between U.S. and Confederate ideologies and beliefs, laid out the Confederacy's causes for declaring secession, and defended the enslavement of African Americans.
in 1865 the Battle of Bentonville, North Carolina had so decimated the forces of Confederate General Joseph E. Johnston that surrendered to William T. Sherman a week after Lee surrendered.
Since RallyPoint truncates survey selection text I am posting events that were not included and then the full text of each survey choice below:
a. March 21, 1863 Union Corps Commander Major General Edwin Vose Sumner dies in Syracuse, NY of natural causes on his way to assume command of the Department of Missouri.
1 March 21, 1861 Missouri secessionist convention adjourns having voted 98-1 against secession
2 March 21, 1861 the Cornerstone Speech, also known as the Cornerstone Address, was an oration delivered by Confederate Vice President Alexander Stephens at the Athenaeum in Savannah, Georgia, on March 21, 1861. Delivered extemporaneously a few weeks before the Confederacy would start the American Civil War by firing on the U.S. Army at Fort Sumter, Stephens' speech explained the fundamental differences between the constitutions of the Confederacy and that of the United States, enumerated contrasts between U.S. and Confederate ideologies and beliefs, laid out the Confederacy's causes for declaring secession, and defended the enslavement of African Americans.
3 March 21, 1864 Abraham Lincoln signs legislation allowing Nevada and Colorado to become states even though they don't meet population requirements.
4 March 21, 1865 Battle of Bentonville, North Carolina, Union Maj. Gen. Joseph A. Mower, commanding the division on the Union right flank, requested permission from his corps commander to launch a "little reconnaissance" to his front, which was granted. Mower instead launched an attack with two brigades on the Confederate left flank, which was defending Mill Creek Bridge.
Overview: Battle of Bentonville, North Carolina [March 19 – 21, 1865] Department of South Carolina, Georgia, and Florida commanded by Lt. Gen. William J. Hardee, D. H. Hill and Army of Tennessee commanded by Lt. Gen. Alexander P. Stewart, combine to attack the left wing (the Army of Georgia) commanded by Maj. Gen. Henry W. Slocum on the federal advance. In spite of achieving initial gains, the Confederates were repulsed. Major General William T. Sherman reinforces Slocum on March 20 and Slocum nearly enveloped the Confederate forces on March 21.
Union Maj. Gen. Joseph A. Mower, commanding the division on the Union right flank, requested permission from his corps commander to launch a "little reconnaissance" to his front, which was granted. Mower instead launched an attack with two brigades on the Confederate left flank, which was defending Mill Creek Bridge. Mower's men managed to come within one mile (1.6 km) of the crossing before Sherman peremptorily ordered them to pull back. In his memoirs, Sherman admitted that this was a mistake and that he missed an opportunity to end the campaign then and there, perhaps capturing Johnston's army entirely. Among the Confederate casualties was Lt. Gen. William J. Hardee's 16-year-old son, Willie. Hardee had reluctantly allowed his son to attach himself to the 8th Texas Cavalry just hours before Mower's attack.
As a result of the overwhelming Union strength and the heavy casualties his army suffered in the battle, Johnston surrendered to Sherman little more than a month later at Bennett Place, near Durham Station. Coupled with Gen. Robert E. Lee's surrender earlier in April, Johnston's surrender represented the effective end of the war.

thanks for the post.

Bentonville was the last major battle, as I understood it, the battle was atypical of the war in the Western Theatre. The South would do very well in the initial stages then be outnumbered and outmanuervered.
