Cannonball found near the Church of Jesus Christ of Latter-day Saints Independence Stake Center and the Community of Christ Temple in Independence, Missouri, in approximately 1990. This solid shot, 2.75-inch projectile was likely fired by a Union Army Parrot Rifle during the Second Battle of Independence (October 21-22, 1864).

On the morning of October 22, Union forces, under the command of Major General Alfred Pleasanton, pursued Confederate General James Fagan's brigades through the community of Independence. Confederate forces attempted to halt the Union onslaught on the high ground of the "Temple Lot." Union Army artillery pieces arrayed on the Temple Lot (to the north and west of the Church of Christ Temple Lot and near the present day Community of Christ Stone Church) laid down heavy artillery fire. Confederate forces were "annihilated" and survivors forced to retreat. Meanwhile, Confederate General James Marmaduke had engaged Pleasanton's Union forces in battle two miles west of Independence, where he repulsed Union forces.

The Second Battle of Independence ended with a Confederate victory. The next day, however, on October 23, 1864, in what became known as the Battle of Westport and is sometimes referred to as the "Gettysburg of the West," thirty-thousand Union and Confederate forces fought a major battle to the west of Independence, in what is now modern Kansas City, Missouri. The Battle of Westport was a victory for Union forces, and effectively ended the Confederate's Missouri campaign.
