Battle of the Clouds, Pennsylvania
The chronology of battles that made up the Philadelphia Campaign of the American Revolution is often limited, in discussion, to three or four events; the Battle of Brandywine, the Paoli Massacre, the Battle of Germantown, and Washington marching his troops into Valley Forge for the winter. But while that may be the highlights, it does little to explain the movements and decisions General George had to make. Many of them were questionable, yet in the end, effective, though much of that may have had luck on his side. For now, let's focus on how we got to the Battle of the Clouds. Washington's troops had escaped capture, but took the loss at Brandywine the week before, but while he marched his troops back toward Philadelphia to protect the capital, the British waited at Brandywine while their supplies were brought forward from their ships at Turkey Point on the Chesapeake Bay. However, the British eventually began to move north, and Washington decided that he should meet them for a general engagement outside the city and away from his supply of munitions west. Let's start there.

Two skirmishes occurred on both ends of the line, but a tropical storm hit, causing Washington to retreat.

Battle of the Clouds, Pennsylvania
Washington's troops had been camped the night before in the valley below the hills where today's Immaculata University and Villa Maria Academy now stands. Washington himself had stayed the night of September 15 at Malin Hall, the home of Randall Malin. The next morning, the Continental Army climbed that hill toward the precipice, past that lone sign at Immaculata, and toward the road between the two academic institutions, West King Road. The British, under Lt. General Sir William Howe were coming up two roads from the Brandywine area, approaching the road that today separates the college and academy. Lt. General Charles Earl Cornwallis was at Seven Stars Tavern.
The ground along the roadbed was relatively flat, and Washington began to array his troops in a battle line as General Howe, moved toward what he thought was Washington's position, White Horse Tavern up Chester Road, Route 352, with Cornwallis following. General Wilhelm von Knyphausen's column was heading north from Brandywine, ... both toward the area of Boot Tavern.
In mid-morning, the first shots were fired on Knyphausen's troops at Turk's Head Tavern (in today's West Chester) by a Continental scouting party. One British soldier was killed and two wounded. Brigadier General Edward Mathew, British, followed the scouting party up Route 100, Pottstown Pike.
Washington began to command his troops at about the same time, sending Maxwell's Light Infantry Corp and Potter's Pennsylvania Militia, about fifteen hundred men, to harden the western approach to White Horse Tavern. Wayne's two brigades, along with an inexperienced Pennsylvania Militia Brigade, about another fifteen hundred men, were ordered to cover the eastern flank along Chester Road.
Suddenly, on the eastern flank, a skirmish battle occurred, even before the Continental Army could get into full position along West King Road. Cornwallis had moved first up Chester Road and encountered the inexperienced Pennsylvania Militia sent out in a skirmish line near Greenhill Road. They fled at first fire, fourteen killed. No British casualties. Wayne's regular troops went unengaged.
It was two to three p.m. before the first action on the western flank occurred; Maxwell in position at Pottstown Pike, Potter behind Boot Tavern. British Colonel Carl von Donop, with the Jaegers, moved forward too quickly and got engaged without support around Boot Tavern with Potter's men. Donop escaped, breaking through with the horsemen to reunite with Knyphausen while fighting Potter's men as they went. Rain began to fall. Weapons began to misfire. The Jaegers drew their swords and Potter's men left the field. Eight to eleven Continental forces were killed in this action versus five for the British.
As each minute passed, the waves of a tropical rainstorm worsened, pelting both sides. Meanwhile, Washington's main forces between Maxwell and Wayne were not yet filled in and he had already lost the two skirmish fights on his flanks. Washington made a quick decision to retreat toward the valley and White Horse Tavern, determining that he could not win this fight in the middle of a northeaster. At 5:00 p.m., the British also called off the attack.

Where Is It
The location of the Battle of the Clouds is on the campuses of Immaculata University (1145 West King Road, Malvern, PA 19345) and Villa Maria Academy, plus the skirmish areas near Boot Tavern and on Chester Road. It is not a historic site, although with permission, you may be able to walk the grounds and sight the sign to the battle. In the valley, there is a Battle of the Clouds Park located at 133 Phoenixville Pike, Malvern, PA 19355, near White Horse Tavern, below which the sign of the encampment and battle sits along the Chester County Trail. Search for the academic institutions to get your bearings as well as the park, which is devoted to recreation, not the battle.
What is There Now
Battle of the Clouds
Not much and it takes your imagination to witness it. If you wanted to hide history, they do an unintentionally good job. The sign to the battle at Immaculata College is in the rear of the main buildings. With permission, walk from the main parking lot, then take a left. The sign on the Chester County Trail is right of the parking lot at the Battle of the Clouds Park. All along the road between the two schools is where the line for Washington's troops extended, although they went unused. You can walk along the road to get a sense of where that is. Yes, there should be more interpretive signs, which is the intention.
When Open and How Much
The grounds are open by permission, with the exception of the Battle of the Clouds Park, which is more a recreation park namesaked to the battle than about it. There is no charge, no visitor center, very little interpretation.
Fees subject to change.

Who and How Many Troops?
A total of twenty-six thousand troops were ready to engage in a full Battle of the Clouds. The British had Washington outnumbered. The Continental Army had circa eleven thousand troops; the British fifteen thousand.
The Continental Army marched into the area led by the light dragoons, followed by the divisions of Major General John Sullivan, Major General Lord Stirling, Major General Anthony Wayne, Brigadier General Francis Nash, Major General Adam Stephen, and Major General Nathanael Greene. On the morning of September 15, Washington reentered Chester County and the Great Valley area. The exact order of march there is unknown, except that Wayne likely led the march with Greene in the rear.
They camped along old Lancaster Road, Route 30, from Exton to Paoli Tavern.
There are some reports that the troop levels ranged from ten thousand Continental Army to eighteen thousand for the British and that around one hundred troops on both sides were killed or wounded.

Vagaries of War
Without the National Weather Service to warn either side that this day, September 16, 1777, was not going to be pleasant for a battle, a substantial tropical storm hit the Philadelphia area that day right as the two skirmishes began and Washington's troops began to array in their battle line. Unfortunately for the Continental Army, their cartridge boxes were not waterproof. The British Regular Army's cartridges boxes were. So the weather, plus the routing of the flanks, caused General Washington to depart the battlefield.
The wet ammunition would have been no good for the Continental Army and a disastrous outcome at the Battle of the Clouds, instead of a minor loss, would have occurred.
"This was a most terrible stroke to us, and owing entirely to the badness of the cartridge-boxes which had been provided for the army," Brigadier General Henry Knox.
Washington would order the retreat back down the slopes and on two roads until they would meet again at Yellow Springs Tavern. It was a slow, sodden retreat, as the agricultural fields and roads had turned to mud. In the future, Washington would order better cartridge boxes.

What Did Washington Do After the Battle
George Washington became consumed with the idea that the British were going after his forges north and west of Malvern, so he first ordered his troops to meet him at Yellow Springs Tavern toward Phoenixville; while there he sent eighteen men under Lt. Colonel Alexander Hamilton and Captain Harry "Lighthorse" Lee to obtain the supplies at Valley Forge before the British could get them. That did not work; the British fought those eighteen men with six hundred troopers in the Battle of Valley Forge. This was three months prior to the encampment there. Yes, there was a battle there, albeit small and quick.
General Washington was still convinced that the British were going west to Warwick Furnace and Reading Foundry, as well as his supply depot in Reading, where his cannons and munitions were made, repaired, and stored. So he left behind General Wayne with one quarter of his troops to monitor British activity, and Washington went west to the furnaces to protect them and repair his guns.
How did that go? Wayne was surprised during a midnight raid of his camp, causing the Paoli Massacre, and Washington would head east to meet Wayne, but still took a British feignt as truth, and settled at Camp Pottsgrove for four days. The British went east instead and took Philadelphia unopposed.
