Some needed introduction.

Such introduction consumed a few minutes, even after the last had come and been checked off on the Master's list, in cipher code.

The brightly lighted room, behind its impenetrable curtains, blued with tobacco-smoke; but no drop of wine or spirits was visible.
The Master, at the head of the table, sat with his list and took account of the gathering.

Each man, as his name was called, gave that name in full, briefly stated his service and mentioned his wound.
All spoke English, though some rather mangled it.

At any rate, this was to be the official language of the expedition, and no other was to be allowed.
