The danger that threatened England at the time (early in 1539) was not really quite so serious as it seemed; for, close as the alliance between Charles and Francis was, old jealousies were not dead, and a joint war against England would have revived them; whilst the Papal plan of treating England commercially as outside the pale of civilisation would have ruined Charles' subject and was impracticable. But, in any case, the peril was real to Henry and Cromwell; and under the stress of it they were driven into the attempted policy of a Protestant confederacy. At the end of January 1539, Christopher Mont was sent to Germany with the first overtures. He carried letters of credence to Philip of Hesse, and Hans Frederick of Saxony, with the ostensible object of asking whether they had come to any conclusion respecting the theological disputations held in the previous year between their envoys and the English bishops to establish a common doctrinal basis. This, of course, was a mere pretext, the real object of the mission being to discover to what extent Henry could depend upon the German Protestant princes if he were attacked by their suzerain the Emperor. A private instruction was given to Mont by Cromwell, to remind one of the Saxon ministers who had come to England of a former conversation about a possible marriage between the young Duke of Cleves and the Princess Mary; and he was to take the opportunity of finding out all he could about the "beauty and qualities, shape, stature, and complexion" of the elder of the two unmarried daughters of the old Duke of Cleves, whose eldest daughter, Sybilla, had married Hans Frederick of Saxony himself, and was as bold a Protestant as he was. At the same time approaches were made to Christian III. of Denmark, who had joined the Evangelical league; and gradually the forces against the Papacy were to be knitted together. An excuse also was found to send English envoys to Cleves itself to offer an alliance in the matter of the Duchy of Gueldres, which the Duke of Cleves had just seized without the Emperor's connivance or consent. Carne and Wotton, the envoys, were also to offer the hand of the Princess Mary to the young Duke, and cautiously to hint at a marriage between his sister Anne and Henry, if conditions were favourable; and, like Mont in Saxony, were to close the ranks of Protestantism around the threatened Henry, from whose Court both the imperial and French ambassadors had now been withdrawn.
