[2] By 1819 he had become surveyor for part of the London to Holyhead road running from Stony Stratford (Buckinghamshire), to Dunchurch (Warwickshire) under the overall direction of Thomas Telford who seems to have had a high regard for Upton's engineering skills.
The day before his trial in July 1826 he absconded and made his way to the Russian legation in London who were keen to recruit engineers for their Black Sea expansion.

John Upton worked extensively in Sevastopol to build a huge set of dry docks for the Russian Black Sea Fleet.
During the Crimean War William Upton was held for a short time by the British military who hoped he would reveal details of Sevastopol harbour defences.
