While Walter Butler does not appear to have been involved with the attempt to assassinate Wallenstein in the NTL, Wallenstein knew of Butler's connection with the successful OTL plot against him. Between that and Wallenstein having made himself king of Bohemia in July of 1633, Butler, along with Walter Devereaux, Robert Geraldin, and Dennis MacDonald left Bohemia and headed west, with a subsidy arranged by Maximilian of Bavaria. By March of 1634, they had reached Bonn and entered the employ of Ferdinand of Bavaria, Archbishop of Cologne and Maximilian's brother.
The four men were sent into the Fulda area, with the goal of abducting Johann Bernhard Schenk von Schweinsberg and bringing him to Bonn, as well as "interviewing" the American administrators of the area. They were able to accomplish this in August, largely because their targets were riding through the area in response to the potential spread of the Ram Rebellion. However, their plans were disrupted when Joel Matowski, who had been with Abbot Schweinsberg and had been tied up and left to die, was found and identified his attackers as having spoken Irish-accented down-time English.
In September of 1634, they arrived back in Bonn to find that Archbishop Ferdinand had left the city, and their regiments were in retreat. They spent the winter in Euskirchen, and while there, Butler's relationship with his wife became somewhat frayed. They left in February of 1635, after it became clear that Ferdinand was unable to continue paying them, and headed for Bavaria to enter the employ of Maximilian. However, they were pursued by a "posse" from the SoTF barracks in Fulda, with help from Nils Brahe, Gustav Horn, and even Bernard of Saxe-Weimar. (The SoTF wanted to put them on trial; the generals were mostly concerned that they not be allowed to reach Bavaria or to run free through Swabia.)
In May of 1635, Butler and Devereaux reached Scharndorf, in Württemberg, but were not far ahead of their pursuers. (Geraldin and MacDonald had been captured before reaching Scharndorf.) That same month, they were captured after a fire that broke out in a cook shop largely destroyed Scharndorf. Butler's wife wanted to go back to Bohemia rather than accompany him to Fulda.
- ↑ While his death is not explicitly written about, he disappears from the series after his capture in "Window of Opportunity".
- ↑ It is not known whether or not she arrived there. Like her husband, she seems to disappear from the series after the events of "Window of Opportunity".
