The original plan on
page 41 was, in Wanda's words, "croak or capture the coalition leader, plus the prisoner, and any other warlords they have taken along. We will also get the Arkenpliers." Then,
klog #5 shows the shift in Parson's focus toward forcing Ansom to come in through the tunnels.
Klog #6 explains the strategy that he came up with for destroying the siege units and achieving the new goal of klog #5. As he's planning it out with Misty's help on
page 47, Wanda comes in and reveals the flaws in Ansom's intel and C&C, at which point Parson says that they can change the whole course of the battle for almost no cost.
Yet, everything that we see up through
page 54 is the plan of klog #6. He didn't need Wanda's revelation to force Ansom to come in through the tunnels and he apparently hasn't given up on that goal either; the difference is that it's now just
"for an opener". Looks to me like he added the original goal back in on top of the new one -- and I could've seen it five pages ago if I'd been paying (even) closer attention!
