If you check this video you can see many Confederate pikes being unearthed. There are also other videos featuring high-tech Confederate pikes. Were these meant just to entertain troops in the field? There are no instances I'm aware of, where the pike was used in anger against the Yankee invader.
EDIT: If you watch the first video, you will see, that the pikes were made in 1865. How could the discussion about their use and their productionmanufacture continue up until the end of the American civil war without actual use in the field?
