Wall served on the English mission in Worcestershire for twenty-two years before being arrested and executed at the time of Titus Oates's alleged plot.

[3] He entered the English College, Rome, on 5 November 1641 and was ordained a Catholic priest on 3 December 1645.

After 22 years of ministry to the Catholics of the area, he was apprehended in December 1678, at Rushock Court near Bromsgrove, where the sheriff's man had come to seek a debtor.

[7] His quartered body was given to his friends and was buried in the cemetery adjoining the Church of St. Oswald of Worcester,[4] while the head was taken to the Franciscan friary of Douai, to which the martyr belonged.

[1] Previously, his feast day was observed within the Franciscan Order on the date of his death, 22 August.

It has been moved and is currently observed on 12 July, a date he shares with his brother friar and fellow martyr, John Jones.
