Nah. It’s not local. Military history is a passion of mine, and anyone studying the Napoleonic Wars needs to learn about how cannon were disabled. Knocking off trunnions was usually the work of sailors or marines raiding batteries, while spiking guns was the kind of thing cavalrymen did when they only had a few minutes between the artillerymen running for cover and the enemy cavalry counterattacking.
Regardless, both were common techniques back then. I was a kid when I read the Hornblower stories; it’s all in there. CS Forester’s description about how to recover from a spiked gun was lucid enough for me to grasp even when I was thirteen.
