This article will consider the mismanagement during the years 1865–1885 of the benefaction made by Thomas Mitchell, a convert and one-time military man, to the Catholic Church in Scotland, as well as a number of other financial difficulties that beset the Church during this period. In doing so, it will reveal how the Scottish bishops, under enormous pressures because of Irish migration, acted in ways not only unbecoming of their offices, but also beyond the scope of both civil and canon law. Yet, as will be seen, the Church was developing as an institution and, in many ways, the difficulties of these years were necessary if it was to re-develop as a fully-fledged and autonomous national Church.
