The letter from Prevost to Cochrane is authentic; the one Prevost intercepts from Fosset to Macomb is false. Those 10,000 reinforcements do not exist. The U.S. Secret Service has forged the letter and entrusted its delivery to “an Irishwoman of Cumberland Head” whom they know to be a double agent; as they hope, she dutifully betrays them and delivers it to Prevost instead of to Macomb.
Andrée does not reply. He will never know, nor we.
Say on then, Muse, for Henry, what you saw and Andrew didn’t at the Battle of Baltimore, which like the Battle of Plattsburgh never quite took place. It is Monday, September 12th, still warm in Maryland and threatening rain. Ross and Cockburn begin their overland advance, pause for breakfast at a convenient farmhouse, and decline the owner’s cautious invitation to return for dinner: he will dine that evening, Ross declares, “in Baltimore or in Hell.” A few hours later, on Cockburn’s advice, he rides back a bit to hurry a light brigade along in support of his advance party, who have got too far ahead of the rest and are meeting the first desultory American fire. As Ross trots down the North Point Road, the anonymous, invisible Americans fire again from their concealment in a grove of oaks. One bullet strikes him in the arm and chest: he falls, he speaks of his wife, he dies. The invasion will go forward, that day and the next, under Ross’s successor and Admiral Cockburn, who commands only his own small band of marines. The American advance line will retreat, but in less disorder than at Bladensburg; they will regroup with the main force of militia at Sam Smith’s earthworks to await the real assault. On Tuesday the 13th Colonel Brooke (the new British commander, even more cautious than his predecessor) and Admiral Cockburn will position their forces before those earthworks and wait for news of Cochrane’s success at Fort McHenry before mounting their attack. And for all of Cockburn’s exasperated urgings, that attack will never be mounted, because that news will never come.
Can you see, Muse, through the rain of that sodden Tuesday, the letters going back and forth between Brooke and Cochrane, army and navy? Cochrane has written Ross on the Monday afternoon that, as best he can see from the river, the flank of Sam Smith’s earthworks may be turned without a frontal assault. His letter comes back that evening unopened, together with the news of Ross’s death. Unperturbed, perhaps relieved, Cochrane orders the body preserved in a cask of Jamaican rum and dashes off encouragement to Colonel Brooke: Prevost says burn, burn; I will take Fort McHenry (the harbor, alas, is blocked with scuttled privateers); you take the city. On Tuesday morning his bomb and rocket ships open fire, out of range of the guns of the fort. Three hours later he is already wavering; another letter goes down the river and up the North Point Road, this one to Brooke via Admiral Cockburn: It appears we cannot help you; the city is too far away, the fort too strong; consider reconsidering whether Brooke should attack at all. But he sustains the one-way bombardment into the afternoon, and the garrison at McHenry must take their punishment without reply. Even Cochrane cannot see the one bombshell out of hundreds and hundreds that lands directly on the powder magazine, goes through its roof with fuse still sputtering and, like the one bullet that felled General Ross, might have rewrit this chapter of history had not a nimble nameless fellow leaped to douse it. Cochrane moves his ships in closer; the Americans at last and jubilantly return the barrage; he moves back out of range. Nothing is working. Here’s a letter from Brooke, fifteen hours late: he will be in Baltimore by noon! But it’s past three, and there’s no sign of action at the earthworks. Cochrane can’t see what you can, Muse: that Brooke has got
