This alliance which seemed to cut off from Henry all hopes of further success, proved in the issue the most favorable event that could have happened for his pretensions.

Whether the dauphin and the duke of Burgundy were ever sincere in their mutual engagements, is uncertain; but very fatal effects resulted from their momentary and seeming union.
The two princes agreed to an interview, in order to concert the means of rendering effectual their common attack on the English; but how both or either of them could with safety venture upon this conference, it seemed somewhat difficult to contrive.

The assassination perpetrated by the duke of Burgundy, and still more his open avowal of the deed, and defence of the doctrine, tended to dissolve all the bands of civil society; and even men of honor, who detested the example, might deem it just, on a favorable opportunity, to retaliate upon the author.

The duke, therefore, who neither dared to give, nor could pretend to expect, any trust, agreed to all the contrivances for mutual security which were proposed by the ministers of the dauphin.
