St. Stephen's Cathedral, Vienna
On the invitation of Walter Butler, then Colonel of an Irish regiment serving in Austria, he left Ireland and remained for some time as chaplain to Butler's regiment. He returned to Ireland twice (1630, 1632), and on the death of Butler he acted as chaplain to Devereux, Butler's successor in the command of the Irish forces fighting under Ferdinand II. He accompanied the troops during several of the campaigns of the Thirty Years' War, and had thus a good opportunity of observing the events recorded in his history of the war. In 1640 he was appointed chaplain to the English, Scotch, and Irish forces in Austria, and continued to hold that position till 1643, when he went to reside at Vienna as a choral vicar of St. Stephen's Cathedral, Vienna. His last book was published in Sulzbach in 1672.
