He had previously performed the stunt in other locations, for example an 1828 history of Dover (Batcheller) records that he "amused the people of Dover, by flying across the harbour, from the highest point of the cliff, towards the lower extremity of Snargate-street .....Thousands were assembled from all parts to view this novel sight." A History of Lincoln (1815) notes that, in this period, he went from a cathedral tower "to the castle hill near the Black Boy Inn"" and another descent from 'Newark spire' in Nottinghamshire.
Cadman walked some 250 metres up the rope that connected the 68-metre-high spire of St Mary's Church with an anchor in the ground in Gay Meadow, Shrewsbury. Climbing up the rope across the River Severn, he performed tricks on the way. When at the top, near the pinnacle of the spire, he donned a wooden breastplate with a central groove and hurtled to earth along the rope.[3]
On 2 February 1739 he fell to his death when the rope broke. He was buried at St Mary's Church, where a commemorative plaque in his memory may still be found by the west entrance. It reads:
Let this small Monument record the name of Cadman, and to future time proclaim How by'n attempt to fly from this high spire across the Sabrine stream he did acquire His fatal end. 'Twas not for want of skill Or courage to perform the task he fell, No, no, a faulty Cord being drawn too tight Hurried his Soul on high to take her flight Which bid the Body here beneath good Night Feb.ry 2nd 1739 aged 28[4]
