Letters! This second of Brooke’s received, unhappy Cochrane replies (to Cockburn) that the plan is folly: the navy can do nothing; McHenry will not fall; New Orleans is a richer city anyroad; retreat. It is Tuesday evening, rain coming down hard now. Cockburn scoffs at this letter — Washington all over again! — and urges Brooke to ignore it: Attack, attack. Brooke’s junior officers are of the same mind; retreats do not earn promotions. But command is heavy: if the army takes the city but the navy cannot take the fort to load prizes, there will be nothing but an expensive bonfire to show for possibly very high losses. If the army fails and the navy succeeds (as seems unlikely), the fall of Fort McHenry will mean nothing. The officers — not including disgusted Cockburn — argue till midnight, when Brooke wearily pens his last to Cochrane: We are following your advice; as the navy cannot take the fort, we shall retreat to North Point and reembark.

But on that same midnight (you can see and say, Muse, what they cannot) — suspecting that Cockburn might persuade Brooke to ignore these letters and attack — Cochrane dispatches after all, reluctantly, the diversionary force Brooke has requested but no longer wants. And here, Henry, our ancestor comes back into the tale. You have seen him, all this while, fretting through the bombardment with Key & Co. back at the main fleet anchorage. He is truly saddened, as you saw, by the news of Ross’s death: the man was overcautious, perhaps, but brave and not bloodthirsty, an officer and gentleman. You have seen Andrew fear for the fate of Baltimore if — as seems likely from Prevost’s letter and Cochrane’s first to Colonel Brooke — Cockburn has his way with the city. Rumors abound like Chesapeake mosquitoes; every dispatch boat leaves its message like a wake behind. Old Dr. Beanes complains he can’t see a thing; Andrew borrows a spyglass from the British lieutenant in charge of them and confirms through the day that Armistead has not yet struck his colors at McHenry. There is a bad moment towards late afternoon, just after the one heavy exchange of fire from the fort, when they lose sight of it, the big 30-by-42-foot Stars and Stripes, in the smoke and rain, and wonder whether after all the fort has died. But John Skinner recollects that there is a second flag there, a smaller “storm flag” for squally weather; he optimistically proposes that the renewed silence means only that the bomb ships have retired back out of range, and that Major Armistead may be using the lull to hoist a banner more appropriate to the wretched weather. Key is unconvinced. Dr. Beanes fears the worst.

Andrew volunteers to find out. He has seen how fretful is their young warden to be upriver with the action. Without much difficulty Andrew has insinuated that his own status is different from that of “the Americans,” some sort of special agency. When the message sails through that Brooke plans a night assault and wants diversionary action west of Fort McHenry, in the “Ferry Branch” of the Patapsco, he declares to the lieutenant that he knows those waters like the back of his hand (he has in fact crossed once on the ferry, in 1803, en route to Joshua Barney’s hotel and Jérôme Bonaparte’s wedding) and pleads to be fetched to Cochrane as a guide. Whether or not the lieutenant believes him, he sees a chance here to move his own career upstream, and so delegates his wardenly duties to a midshipman and fetches Andrew in a gig to the Surprize.

The Americans are indignant; Key in particular feels himself imposed upon, though he has never quite taken our forefather at face value, and though Andrew has done his hasty best to intimate that this present defection is another ruse. When Andrew presses on him a hurriedly penned note “in case we see each other no more,” Key at first will have none of it. But there is a winking look in the fellow’s eye… At last he stuffs the letter into his waistcoat and turns his back; Skinner and Beanes shake their fists at the departing gig.

Colonel Brooke’s final message, that he is withdrawing, has yet to be written, much less delivered. It seems likely to Andrew that Cockburn may prevail and the attack succeed, especially with the help of this new tactic; he is resolved therefore to do what he can to divert the diversion. What with the firing ceased and the rain still falling, the night is dead black. There is no need even to make his case to Admiral Cochrane: their gig is taken at once for one of the little flotilla assembling about the Surprize under general command of Captain Napier, and the lieutenant stays mum, recognizing the opportunity. Twenty small boats with muffled oars and light artillery, about fifteen men to a vessel, they head out at midnight in a quiet file. Andrew’s boat is ninth in line: a single tap on the lieutenant’s shoulder (even whispered conversation is forbidden) is enough to turn them and the eleven boats behind them up the wrong river-branch almost at once, into the line of scuttled ships across the harbor mouth. The lieutenant presently sees their peril — they are right under the guns of the fort! — but cannot proclaim it or denounce its cause; he gets the boats somehow turned about and headed back towards the Surprize.

Having assumed the lead, now they are in the rear of the line. Once out of earshot of the fort, and before the lieutenant can say anything, Andrew whispers angrily that his signal was misread. The other boats are clearly glad to abandon the mission; their crews are already scrambling home. The lieutenant must turn at once into the west, the left, the port, the Ferry Branch, and catch up with Napier, who in that darkness cannot even know that he now has nine boats instead of twenty. No time to argue: it’s that or explain to Admiral Cochrane what they’re doing there in the first place. They go — west, left, port — past looming dark McHenry and opposite the smaller forts Babcock and Covington. In their haste they make a bit of noise. No matter: it’s 1:00 A.M. now on Wednesday the 14th, and Cochrane recommences, per plan, his bombardment of Fort McHenry. Under cover of that tremendous racket and guided by bombshell light, they actually locate and join Napier’s reduced flotilla at anchor.

By that same light the captain is just now seeing what’s what and clapping his brow. The shore gunners see too, from the ramparts of Babcock and Covington, and open fire. Napier gives the signal to do what they’re there for; the nine boats let go with all they’ve got. Fort McHenry responds; the bomb and rocket ships intensify their barrage. For an hour the din and fireworks are beyond belief; if Brooke’s army needs a diversion, they’ve got it!

And the Ferry Branch is no place to be. Andrew sits in the gig’s stern sheets, stunned by the barrage. 18-pounders roar past to send up geysers all around; they will all die any moment. He has hoped the diversion would include a landing, so that (his credibility with Cochrane gone) he might slip away in the dark and commence the long trek back to Castines Hundred; now he considers whether swimming to shore is more dangerous than staying where he is. At 3:00 A.M., by some miracle, Napier has yet to lose a boat or a man. But their position is suicidal, and there is no sign of Brooke’s expected attack over beyond the city: those earthworks are deathly quiet. The captain cannot see that three miles away Brooke’s sleeping army has been bugled up and fallen in, not to assault the city but — to their own astonishment and the chagrin of their officers — to begin their two-day withdrawal to North Point, minus three dozen prisoners and 200 deserters. Napier has done all he can. He gives the signal (by hooded lantern) to retire.

They proceed back down the Ferry Branch as they came, along the farther shore from McHenry, whose gunners now lose them in the darkness and cease their fire. It looks as though Captain Napier, against all probability, will complete his assignment without casualties. Andrew tests the water with his hand: very warm in the cool night air. “We must signal the fleet we’re coming,” he whispers to the lieutenant, “or they’ll take us for Yankees,” and without asking permission he snatches up the launcher and fires a rocket to the Surprize. As he intends, it is seen at once by the Fort McHenry gunners as well as by the fleet. The lieutenant wrestles him down; the world explodes; the boat beside them goes up in shouts and splinters. All the batteries of Fort McHenry let loose, and flights of British rockets and bombshells respond. Andrew gets to his knees in the bilges among the straining, swearing oarsmen. His last sights are of the lieutenant scrambling for a pistol to shoot him with; of Major Armistead’s cannon-riddled storm flag — sodden and limp, but lit by the shellbursts over the McHenry ramparts — and of a misaimed Congreve whizzing their way, some piece of which (or of oar, or of gunwale) strikes him smartly abaft the right temple, just over the ear, as he dives into the bath-warm river.
