On Friday morning they entered the Delaware river, and with favoring wind and tide, sailed up beyond fort Casimir, and landed their forces about a mile above.  A flag of truce was promptly sent to the fort, demanding “the direct restitution of our own property.”  Some parleying occupied the time during the day, while Stuyvesant was landing his batteries.  The next morning the Swedish commander, convinced of the folly of any further attempt at resistance, went on board the Balance and signed a capitulation.  The victor was generous in his terms.  The Swedes were allowed to remove their artillery; twelve men were to march out with full arms and accoutrements; all the rest retained their side-arms, and the officers held their personal property.

At noon the Dutch, with pealing bugles and flying banners again entered upon possession of the fort.  Many of the Swedes took the oath of allegiance to the New Netherland government.  The next day was Sunday.  Chaplain Megapolensis preached a sermon to the troops.  But a short distance above fort Casimir there was another Swedish fort called Christina.  It was not denied that the Swedes had a legitimate title to that land.  Indeed after the Company in Holland had sent directions to Stuyvesant to drive the Swedes from the river, they sent to him another order modifying these instructions.  In this dispatch they said: 

“You may allow the Swedes to hold the land on which fort Christina is built, with a garden to cultivate the tobacco, because it appears that they made this purchase with the previous consent of the Company, provided said Swedes will conduct themselves as good subjects of our government.”

But the Swedish Governor, Rising, having lost fort Casimir, re-assembled his forces and strengthened his position in Fort Christina, which was two miles farther up the river.  This fort was about thirty-five miles below the present site of Philadelphia, on a small stream called Christina creek.  The fleet anchored at the mouth of the Brandywine, and invested the fort on all sides.  The Swedes outside of the fort were ruthlessly pillaged; a battery was erected and the fort summoned to surrender.  Resistance was hopeless.  The articles of capitulation were soon signed between the victor and the vanquished.

“The Swedes marched out with their arms, colors flying, matches lighted, drums beating and fifes playing; and the Dutch took possession of the fort, hauled down the Swedish flag and hoisted their own.”

The Swedes, who to the number of about two hundred had settled in that vicinity, were allowed to remain in the country, if they wished to do so, upon condition of taking the oath of allegiance to the Dutch authorities.  Thus the Swedish dominion on the South river was brought to an end.  This was the most powerful military expedition which had ever moved from any of the colonies.  The Swedes had held their independent position on the Delaware but about seventeen years.  Leaving an agent, as temporary commandant, Stuyvesant returned triumphantly to fort Amsterdam.
