From Percy Longhurst’s “JiuJitsu and Other Methods of Self Defence”, 1906 (pp 77-78):
A different defence to a similar attack – one which considerably surprised me when I was first introduced to it by Mr. Barton-Wright several years ago, and which is by no means too much for feminine strength – is that illustrated in Figure 46. The descending hand of the assailant is jerked up, his wrist seized, and the defender simultaneously steps outside the assailant’s advanced leg so that her knee – the leg being bent – is pressed against his bent knee. A sideways and downwards jerk of the captured hand will lay the assaulter on the ground, the whole secret of the move being, of course, the disturbance of the balance.
Considerable confidence and great quickness are required for the satisfactory accomplishment of this throw, and, admittedly, there are better defences which may be used if the assailant has a very great superiority of weight. If the thrower makes a slight backwards kick with her advanced foot at the same moment that she jerks the captured arm round, it will facilitate her assailant’s downfall.
