Which two battles were important confederate victories?

The battles of Fredericksburg and Chancellorsville

Explanation:

As you may already know, the Confederates were a group formed by the southern states, which wished to separate themselves from the USA, forming an independent country with an economy based on the agrarian system and slave labor.

During the war of secession, two important battles for this group were the battles of Fredericksburg and Chancellorsville.

The Battle of Fredericksburg took place between 11 and 15 December 1862. It was commanded by General Robert Edward Lee and the Union Army of the Potomac. This battle is considered a great victory for the confederates because it resulted in a large number of casualties in the army of the union, ending the campaign formed by the northern states of the country.

The Battle of Chancellorsville also promoted the Confederates' victory, allowing them to reach the Union's lines of defense east of Richmond. This battle took place from April 30 to May 6, 1863, in Spotsylvania County, Virginia.
