These monsters chose to block the road in an area that wasn't too perilous, at least not one of those dangerous stretches flanked by canyons on both sides.
If it truly were such a stretch, the merchants' every move would have been extremely cautious, and they would definitely have dispatched scouting knights to search the surroundings over and over.
But it also wasn't conducive to the merchants forming their wagons into a defensive circle; there was no open space nearby, and once three or five wagons were grouped together, they would be squeezed close, even making it difficult for the armed knights to maneuver.
In the current situation, the best response was to rely on the wagons, stand one's ground, provide long-range support, and leave the rest to the armed cavalry.
