When a sentry halted him he would, with great care and with an air of confidence, unfold this permit, and with a proud smile point at the red seal.

The sentry, who could not read English, would invariably salute the coat of arms of his ally, and wave us forward.
That we were with allied armies instead of with one was a great help.
We would play one against the other.

When a French officer halted us we would not show him a French pass but a Belgian one, or one in English, and out of courtesy to his ally he would permit us to proceed.
But our greatest asset always was a newspaper.

After a man has been in a dirt trench for two weeks, absolutely cut off from the entire world, and when that entire world is at war, for a newspaper he will give his shoes and his blanket.
The Paris papers were printed on a single sheet and would pack as close as bank-notes.

We never left Paris without several hundred of them, but lest we might be mobbed we showed only one.
