During a campaign rally in South Carolina on Friday night, Donald Trump fired up the crowd with a story about General John Pershing lining up 50 Muslims and shooting 49 of them with bullets dipped in pig's blood:

“He took 50 bullets and dipped them in pig’s blood. And he had his men load his rifles, and he lined up the 50 people, and they shot 49 of those people, and the 50th person — he said, ‘You go back to your people and you tell them what happened.’

And for 25 years, there wasn’t a problem. For 25 years there wasn’t a problem. All right? So we better start getting tough.”

The urban legend goes like this, as recounted by Snopes:

It happened in the Philippines about 1911, when Gen. John J. Pershing was in command of the garrison. There had been numerous Islamic terrorist attacks, so “Black Jack” told his boys to catch the perps and teach them a lesson.

Forced to dig their own graves, the terrorists were all tied to posts, execution style. The US soldiers then brought in pigs and slaughtered them, rubbing their bullets in the blood and fat. Thus, the terrorists were terrorized; they saw that they would be contaminated with hogs' blood. This would mean that they could not enter Heaven, even if they died as terrorist martyrs.

All but one was shot, their bodies dumped into the grave, and the hog guts dumped atop the bodies. The lone survivor was allowed to escape back to the terrorist camp and tell his brethren what happened to the others. This brought a stop to terrorism in the Philippines for the next 50 years.

He ended the story by telling the raucous crowd: “By the way, this is something you can read in the history books."
