Reminds me of the poem in the Scarlet Pimpernel, a really great movie of heroism of one called the Scarlet Pimpernel who who rescued the condemned under the noses of French during the Jacobean bloodbath of the French Revolution. (Of course, in this case, it's the Germans that can't find Patton.)
"We seek him here, we seek him there Those Frenchies seek him everywhere! Is he in heaven? Or is he in hell? That demmed Elusive Pimpernel?"
I should think Patton would want to have his staff and HQ in France in advance to begin preparing plans for when 3rd Army went operational.
