I like how you Brits dipped your bullets in pig fat.
You make it sound as if it were deliberate. The British Army used animal lard (usually pig) to grease the bullet inside the cartridge for many years as standard practice in all theatres of war or garrison. The action of biting off the paper end of the cartridge and spitting the bullet into the musket barrel was one of the contributory factors in the Indian Mutiny when it was discovered by the Bengalis that pig fat was involved.
For more deliberate use of pig as a weapon against Muslims, you have to look perhaps at the (alleged) actions of 'Black Jack' Pershing, one of yours, who threatened to shoot Muslims with bullets dipped in pig fat and blood and bury their bodies in pigskin, circa 1911.
However, this remains unverified to this day despite many documented rumours, and you know what that means.
