The Burmese court may have been counting on another limited border war but the emperor now ordered an invasion of northern Burma .

Although the king 's three sons were viceroys of the nearby Lower Burma cities ( in Bassein ( <unk> ) , <unk> ( <unk> ) , and <unk> ) , the king , preoccupied with much more serious threat in the north , did not ( or could not ) take any action on <unk> .
