Each goon grabbed the biggest slave they could get, using them as shields moving forward.
"HAHAHAHAH!" The Guia guards laughed as they entered the scope of the sentries, but without an arrow heading towards him. "The Lord is a genius!"

Sentries worked by sight, so if a target was blocked it would not attack. But could the body of a small slave really cover a hostile force effectively?
Despite the relative success of the plan, there were times when it failed. Even, because many felt overconfident the plan would work, they ended up exposing themselves more to the sentry on another side. This was especially true in areas where two sentries shared a scope!
They tended to forget about it, because territories generally didn't have the money to have overlapping sentries!
