On Tuesday morning, April 13, 1858, he left his study at Brookfield, near Conshohoken (near Philadelphia) to look at the operation of a corn shelling machine in the vicinity. Stepping on the inclined plane, he placed his hand on that portion of the instrument known as "the mule," which spread out the corn. His dressing gown became entangled in the wheels of the apparatus, which lacerated his arm in the most frightful manner, from the elbow to the shoulder, severing the main artery and vein, and inflicting the most excruciating pain. He immediately, with great presence of mind, ordered the attendants to bid up his arm tightly, and he was born to the house very mush exhausted by his great loss of blood. Two physicians were called, one from Conshohoken and one from Morristown. The remained with him all night and rendered every assistance in their power. His death, on April 19, was felt a very serious loss to the Episcopal Church, so promptly had he made his mark neither less gifted nor less undaunted in coping with the problems of the day than his distinguished father.

Tyng has an interesting story. In 1854, he took over as pastor of the Church of the Epiphany in Philadelphia when his father retired. But Dudley, unlike his more moderate father, was a committed abolitionist. Just two years later, his preaching against slavery resulted in his being forced to resign. With a few loyal followers, he then organized the Church of the Covenant in that same city. In 1858, he held a rally for fathers and sons, and 5,000 attended. He concluded the event with this: "I would rather this right arm be amputated at the trunk than that I should come short of my duty to you in delivering God's message."

It was only two weeks later that Tyng, visiting a congregant's farm, and watching the thrasher work, got his sleeve caught in that machine. His arm was pulled into the thrasher and torn from its socket. Just a few days later, his arm was amputated at the shoulder. Before he died days a few days later, he told his father to "stand up for Jesus." His final words soon became a popular hymn that is still sung today: "Stand Up, Stand Up For Jesus."
