The British 'response' to the Great Indian Mutiny of 1857-1859 was just as brutal, going so far to strap captured mutineers to the muzzles of artillery pieces and then firing them. The result was said to be 'spectacular.'

The Mutiny is a little ‘off topic’ for this forum. It was characterised by tremendous viciousness, including on civilians and soldier’s dependents. It was this that sparked the use of artillery for executions. Technically, it was no less swift than firing squad. The real deterrence is that it denied the mutineer a body for funeral rites.
