I went to see that most impregnable town and fort of Hysdune ((Heusden -GS)), where I was exceedingly obliged to one Colonel Crombe, the lieutenant-governor, who would needs make me accept the honor of being captain of the watch, and to give the word this night. The fortification is very irregular, but esteemed one of the most considerable for strength and situation in the Netherlands. We departed toward Gorcum. Here Sir Kenelm Digby, traveling toward Cologne, met us.
