on the warpath, to be/go

To be infuriated enough to seek out the person or agency responsible. This Native American term was used quite literally by James Fenimore Cooper in The Deerslayer (1841) to describe a character who had never engaged in battle (“He has never been on a warpath”). By the end of the nineteenth century it was loosely used to describe anyone on an angry rampage.

His nation would not go on the warpath, because they did not think it well, but their friends have remembered where they lived."
