The term _invected_ or _invecked_ is the precise opposite of engrailed. It is similarly composed of small semicircles, but the points are turned inwards instead of outwards, so that it is no more than the exact reverse of engrailed, and all the regulations concerning the one need to be observed concerning the other, with the proviso that they are reversed. {93} The partition line _embattled_ has certain peculiarities of its own. When dividing the field there can be no difficulty about it, inasmuch as the crenellations are equally inwards and outwards from any point, and it should be noted that the term "crenellé" is almost as often used as "embattled." When, however, the term describes an ordinary, certain points have to be borne in mind. The fess or the bar embattled is drawn with the crenellations _on the upper side_ only, the under edge being plain unless the ordinary is described both as "embattled and counter-embattled." Similarly a chevron is only crenellated on the upper edge unless it is described as both embattled and counter-embattled, but a pale embattled is crenellated on both edges as is the cross or saltire. Strictly speaking, a bend embattled is crenellated upon the upper edge only, though with regard to this ordinary there is much laxity of practice. I have never come across a pile embattled; but it would naturally be embattled on both edges. Some writers make a distinction between embattled and bretessed, giving to the former term the meaning that the embattlements on the one side are opposed to the indentations on the other, and using the term bretessed to signify that embattlements are opposite embattlements and indentations opposite indentations. I am doubtful as to the accuracy of this distinction, because the French term bretessé means only counter-embattled.
