The ranking sergeant had turned his purple face to the south. For a moment MacIan was wary of being spied in the lieutenant’s window. But the sergeant was not looking his way; his gaze was directed, rather, towards Cold Harbour—no, towards Bloody Tower, the chief portal to Water Lane from where he stood. MacIan could not see what the sergeant was looking at, but he could discern from the man’s silence, and his posture, that he was soaking up commands. It must be the officer in command of this company. That would fit. The lieutenant, on hearing the guns on the river, and the alarm from the Wharf, would run to investigate. Seeing the improbable, the unthinkable, but not-to-be-denied sight of a party of French Marines bearing down on the Wharf and blazing away with swivel-guns, he would dash back across Water Lane and get in view of the Parade the quickest possible way, which was through the stalwart arch in the base of Bloody Tower, and order all available units to "follow me!"
