Commentary
A krucke siege is introduced here. On the first page, we are also told what the besieger should do immediatelly after krucke. This is later shown in a separate play. In order to prevent this danger, the defender should bind above the besieger's sword either immediatelly (which means he defends by schutzen) or a step later (so he defends by the shield only, but then performs a rebind to take control over the attacker's blade).
On the second page, the play of binder and the bound is introduced here. This time probably just as a warning about what the besieger can do (he may use a technique that leaves the bind).
The besieger instead performs a frontal arms grab, possibly because the priest was pushing forward too much. A way into this grapple should involve switching into priest's special longpoint, but it is not mentioned here. Possibly because we don't need to think about priest's special longpoint unless the opponent tries to resist the grab, which he doesn't in this play.
In the last image, the play shows us how the priest defend's attacker's attempt of arms grab. He checks the attackers shield hand with a schiltslack, which prevents the attacker from wrapping his arm around the priest's arms. At the same time, the priest uses the situation for a strike to the attacker's head.
