The Confederate double barrel canon

The Double Barrel canon was an Civil War invention created during the civil war and was a failure nut its legacy has not died out.
== Origins ==
designs of the double barrel canon dates back to 1642https://en.wikipedia.org/wiki/Double-barreled_cannon but it would be made in 1862 by John Gileland to kill multiple troops at once. How the canon worked is that it shoots two canon balls connected by a chain.
== Test ==
John lead the tested the canon 3 times trying to hit to post which represented union soldiers resulting in the canon balls hitting trees, corn, a cabin, and a cow which died on impact. he considered this a success and petitioned it to several confederate military's leaders which failed and it was shot one last time July 2nd of 1864 were it was used to alter confederate troops of union soldiers but it was a false alarm.https://www.youtube.com/watch?v=7kkyUyPbZcw&t=46s
