Maybe you should.

The First Battle of Bull Run, also known as First Manassas (the name used by Confederate forces), was fought on July 21, 1861

From Wikipedia (it is correct in this case) [my red bold below]:

"The First Battle of Bull Run, also known as First Manassas (the name used by Confederate forces), was fought on July 21, 1861, in Prince William County, Virginia, near the city of Manassas. It was the first major land battle of the American Civil War."

The only soldiers invading the other side's land were Northern soldiers invading Virginia.
