On July 3, 1863, Confederate forces led by General Robert E. Lee attacked Union forces at the Battle of Gettysburg. Among them was the 28th Virginia Infantry Regiment. On the other side, Union defenders included the 1st Minnesota Infantry Regiment.
When the dust cleared, Minnesota had control of the 28th Virginia Infantry Regiment’s “battle flag,” that Confederate rebel flag we all know and properly hate today. Now, 160 years later, the two states are still fighting over that darn flag.
