Continued from the previous plate, and a continuation of the upper shield.
The upper shield is a dangerous position, because both your arms are occupied. This technique allows to disarm the enemy in a manner similar to plate 170.
Here, some continuations to the upper shield from Codex Wallerstein, by request from the audience.
Push aside and stab (note: I recommend gripping the dagger solidly)
Technically this technique is not in Wallerstein, but there is a similar-looking one from the lower shield.
Catch the head (note: make sure his elbow is caught between your arms)
