As usual, things begin to fall apart before any satisfactory conclusion can be reached.
The "Buster" part of all this, as they say, is based on a true story. There are times when everything goes pear-shaped and victory falls into the lap of somebody who was being sidelined by the original plan. I never did find out if it was Machiavellian scheming that won the day, or just an inability to see the plan through. Bit of both, probably.
