Battle of Long Island

Two hundred and forty-five years ago, the fate of Washington’s army—in fact, the fate of the entire Revolution—lay on the muscled shoulders of the fishermen and sailors of the Marblehead Regiment.

A remarkable amphibious evacuation including a miraculous fog would create one of the greatest escapes in military history. On August 27, 1776, the Americans had lost several significant engagements in Brooklyn. The British and Hessians had Washington’s army trapped with their backs to the East River, and it looked like the Revolution might end just weeks after the signing of the Declaration of Independence.

The evacuation was set up two days earlier by an epic stand, an American Thermopylae, which initially saved Washington’s army from the British onslaught. An audacious, suicidal charge by a regiment of Marylanders, known as Washington’s Immortals, bought Washington’s army a precious hour. Had the Marylanders not made their stand and General Howe, the British commander, pressed the attack on the American forts in Brooklyn Heights that afternoon, all the circumstances would have been aligned for a crushing American defeat.

The reprieve would not last long. A nor’easter had pelted both armies for two days. The British had constructed siege lines and entrenchments around the American defenses. The Royal Navy planned to sail behind these defenses and cut off their escape, but the weather, wind, and tides refused to cooperate.

Washington then decided to evacuate Brooklyn and retreat to Manhattan. A mile-wide East River and the British Navy separated the two. The Marbleheaders faced the monumental task of transporting Washington’s men and materiel under the cover of darkness to screen their movement from watchful British eyes.

The Americans not only had tens of thousands of British regulars and Hessian troops arrayed in front of them, but they would also need to pit their skills and strength against three extremely potent natural enemies: time, wind, and tide.

The Marbleheaders were the right men in the right place at the right time in history. For years, they had worked together as a team fishing in the Grand Banks in the icy Atlantic waters off Nova Scotia. These men, their leadership, their grit, and their priceless experience sailing the most treacherous waters in the world would be indispensable in accomplishing the near-impossible that night.

It was the middle of summer; therefore, the night would be short. Amphibious operations and disengagement under pressure are some of the most complex and dangerous in warfare. Even with a rearguard, the Americans rendered themselves vulnerable as they departed their defenses and boarded the boats. A British night attack might prove unstoppable.

Led by Colonel John Glover, the uniquely diverse Marblehead regiment was made up of men “having been brought up to the Seas” and included African Americans, a Spaniard, Native Americans, the young and old. The group forged bonds of steel evident even to outsiders which undoubtedly helped them accomplish the near-impossible task. Multiple family ties ran throughout the regiment, as well, including those of several father-and-son teams like Captain William Courtis and his son Private William Courtis Jr. or Captain Thomas Grant who was joined by his 12-yr-old fifer son, Thomas Grant Jr.

A historian of the day noted, “It was evident that this small reinforcement, inspired no inconsiderable degree of confidence. The faces that had been saddened by the disasters of yesterday, assumed the gleam of animation, on our approach, accompanied with a murmur of approbation in the spectators occasionally greeting each other with the remark, that ‘these were the lads that might do something.’”

Their untold story is in the new bestselling book, The Indispensables: Marblehead’s Diverse Soldier-Mariners Who Shaped the Country, Formed the Navy, and Rowed Washington Across the Delaware. The book is a Band of Brothers-style treatment of this unique group of Americans who changed the course of history.

The first boats manned by the Marbleheaders to make the crossing did not carry troops but horses, ammunition, cannons, and baggage. The decision to transport equipment, guns, and ammunition first had two significant consequences. First, it postponed the notification of the men about the retreat for as long as possible, decreasing the likelihood that word of the covert plan would reach the British. Second, it left the army without the ammunition and guns they would need to continue to hold out against the enemy, making retreat the only option.

In complete darkness, the soldier-mariners had to quickly acquaint themselves with the motley collection of sailing and rowed vessels assembled. Even the minimal light from a shuttered lantern might tip off the British about the operation underway. The sailors had to trust their instincts and nautical knowledge to guide them successfully in the mile-long journey across the river. The mariners took extraordinary measures to ensure secrecy and prevent the discovery of their clandestine mission, including wrapping their oars in cloth to minimize the sound they made dipping into the water. At any moment the British navy could sail up the East River and blow Glover’s motley flotilla out of the water. Miraculously, the wind never shifted in the direction to power the British sails up the river.

At approximately 10:00 p.m., Brigadier General Alexander McDougall gave the order to begin transporting the troops. Glover and his men moved the sick and injured to the boats first. After making the crossing and returning, they transported the Marylanders and other units which remained in the rear guard. To maintain secrecy as long as possible, the men were instructed not to speak or even cough. Orders were communicated in whispers. The soldiers had no idea where they were going until they boarded the boats.

While the soldiers could not ascertain where they were going or why, some of the Loyalists who lived in Brooklyn knew exactly what was afoot. According to legend, staunch Loyalist Catrina Rapalje sent her enslaved black servant to warn the British soldiers that Washington’s army was escaping. If her message had gotten through the chain of command, and the British had attacked, the course of the Revolution would have been altered at that moment, but a language barrier prevented the Dutch-speaking slave from delivering the communications in time. The man had the misfortune of first encountering a group of Hessians who did not speak English. The Germans did not take him to a British officer until late the next morning. By then, it was too late.

In the early hours of the crossing, fortune appeared to favor the Americans. Carefully, the Marbleheaders dipped their cloth-coated oars into the murky, cold waters of the East River. The tide and the winds collaborated to push the boats swiftly across the waterway, and over the next two hours, Glover and his men made multiple crossings. One sailor recalled making a breathtaking eleven trips. Then the tide shifted, and their luck turned.

With every stroke of their oars, the Marbleheaders now fought against Mother Nature, who seemed hell-bent on sending the Americans downriver and into the clutches of the Royal Navy. For the sail-powered sloops, the combination of wind and tide proved insurmountable. Despite the best efforts of the expert seamen, the Marbleheaders nearly lost control of their vessels on their return trip across the river.

The weather and swirling river placed the evacuation in immediate peril. Glover’s men could not possibly deliver everyone across before morning using only the rowed boats. General McDougall sent Colonel William Grayson, one of Washington’s aides-de-camp, to find the commander in chief and apprise him of their situation. McDougall was of the opinion that a retreat was no longer possible.

Fortuitously, Grayson could not find Washington, so McDougall proceeded with the retreat. Before midnight, the fickle winds shifted again, making it possible to return the sloops to service. Once again, a series of the smallest details tipped favorably toward the Americans. Had Rapalje’s servant spoken clear English or encountered British soldiers rather than the German-speaking Hessians first, had Grayson found Washington, or had the wind not shifted a second time, history could have turned out far differently. Despite the wind shift, however, the Americans had lost precious time. Dawn was coming and with it the British Army.

 At the embarkation point, chaos ensued. The troops now understood the necessity of returning to New York if they wanted to survive, and they rushed to get into the boats when their turns came. The sight of the men fighting for a place on the boats enraged Washington. Displaying his enormous strength, the commander in chief picked up the biggest rock he could find, stood near one of the vessels, and threatened to “sink it to hell” unless the men who had pushed others aside got out of the boat. The show of force immediately restored order.

The Marblehead soldier-mariners worked through the night and accomplished an ostensibly impossible task, transporting most of the Continental Army—thousands of men—across the East River in just nine hours. However, even this was not enough. When the first rays of dawn crept over the entrenchments, Americans were still manning fortifications. For those who remained in the trenches, the approach of daylight brought the chance of a renewed attack from the British—and certain death.

But then a thick fog miraculously appeared and cloaked the rest of the escape.

One of the soldiers who made the crossing in the early morning recalled that the water, which had been so turbulent the night before, was smooth as the fog rose with the dawn. The deus ex machina fog at exactly the right time and place proved crucial to saving the United States.

Among the last to cross the river was the commander in chief himself. Washington’s leadership proved as vital to the operation as the fog, the shift in the wind, the skill of the Marbleheader soldier-mariners, and all the other variables that combined to save the American army that day. Disregarding the concern of his officers for his own personal safety, the general stayed behind until the first rays of dawn at 6:00 a.m. to oversee the retreat and encourage the men. British troops did not discover the evacuation until nearly everyone was safely away.

Many Americans of the time saw the hand of God in the perfect timing and execution of the retreat. “Had it not been for the providential shifting of the wind, not more than half the army could possibly have crossed, and the remainder… must inevitably have fallen into the enemy’s hand. Had it not been also for that heavenly messenger, the fog, to cover the first desertion of the lines, …they must have sustained considerable losses.”

They could have added to that list of remarkable circumstances that made the famous crossing possible the indispensable men of Marblehead. A contemporary later observed, “This event, one of the most remarkable in the war, did much toward establishing the fame of Washington and confidence in his ability as a military leader. It would, however, have been impossible but for the skill and activity of Glover and his Marblehead Regiment.”
