An obsolete form meaning to put in peril or to destroy; to ruin or cause to perish.
From em- + perish, or possibly related to 'emperil.' A rare variant that combines em- with the verb 'perish' or its meanings.
This word is so obscure that it barely appears in historical texts—it's almost like a Frankenstein creation of English word-formation, combining em- with 'perish' in a way that never quite caught on.
