Which of the prophets told the Israelites that they should not want a king because he would send their sons to war as well as do various and sundry other nasty things?
Samuel in I Samuel 8 (v 11-18 is the list of nasty things that kings do.)
Technically speaking, Samuel was not a prophet (in the sense that Isaiah, Daniel, et al are grouped together as “the prophets”). Samuel was one of the judges whom God established to rule Israel so they could have no king but God.
He may have spoken prophetically, but his role in the scheme of things was judge.
True, his primary function may have been as a Judge, but the Talmud lists him among the prophets as well (and, to take us off track, Daniel is not among them).

It should also be noted that Samuel was merely paraphrasing and repeating the words of Moses, who says much the same thing in Deuteronomy (I don’t have a text handy, someone can give the citation.)
