Spiking the artillery is the process of jamming a nail or prong into a cannon’s touch hole to render it inoperable for an enemy.
Retreating troops often did this so that captured canons could not be turned on them.
Sometimes attacking troops did this to enemy guns if they believed their charged would be reversed.
Part of the blame for Napoleon’s loss at Waterloo was his troops failed to spike the British artillery, which was repossessed in a British charge and trained on the French.
The devil has spiked Christian guns when he gets us out of prayer.
