I have investigated this matter myself over the years and it just doesn't seem creditable. Where did the battery come from and what was it? Was it an arsenal acquisition of flare and signal rockets, which may be believeable; but which arsenal? Coopers letters containing ordnance records just doesn't mention anything. Shelby's brigade was still in organization at the time of 1st Newtonia and hadn't even been issued much in the way of wagons.
