Was it often in the historical dueling with rapiers and small swords, that after receiving the fatal thrust, the mortally wounded swordsman would step further and deliberately impale himself deeper on the opponent’s blade, in order to close the distance, fix the hostile sword in his own chest, and deliver after blow in the last effort?
I would underline: I do not consider here the mutual kill ("ai uchi") attitude adopted from the start, but a reaction of the wounded fencer, who wants to return blow before bleeding death.
Did many fencers adopt such a tactic, when they realised they were already dying? I read about the similar case in Dubious quick kill - three, where the mortally wounded Duke continued fighting with the hostile blade in his chest, and finally he impaled his opponent, so both were transfixed by each other swords.
The desperate struggle of these fencers may seem odd. However sometimes such reation makes sense: If you are already mortally hit, you do not need to be afraid of your opponent's sword any more, so you can charge at him without any reservation. You do not care about any hurt. The adrenaline help you to cope with pain, and let you boldly take a step forward when cold steel is piercing deeply your chest, but at this cost you can hit your adversary in turn.
Was it difficult for the wounded fencer to block the opponent's sword in his chest? And then, was it easy for him to return blow if he was not taking aslo a dagger? On which factors the success of such tictic could depend on?
