A 1655 Swedish map shows the fort on the west bank of the Schuylkill River, on Providence Island, just south of Minquas, also known as Eagle's Nest or Mingo Creek.[1] Scharf & Westcott put it on the east bank of the Schuylkill River, opposite Minquas Creek.[2] A 1770s map of Philadelphia's naval defenses shows a fort on the island, but it is unidentified.
Directly adjacent to (or opposite) the fort was the terminus of the Great Minquas Path, an 80-mile (130 km) trail from the Susquehanna River to the Schuylkill River. This was the primary trade route for furs from the Susquehannock people, and the Dutch named the trail "Beversreede" or "Beaver Road."[3]
The Swedes had a competing claim for land at the mouth of the Schuylkill River, and they often vandalized Fort Beversreede. In 1648, they built a stockaded 30-by-20-foot blockhouse directly in front of it, called Fort Nya Korsholm. The Swedish building was said to be only twelve feet from the gate of the Dutch fort.[4] It was meant to intimidate the Dutch residents and intercept trade.[5]
In 1651, the Dutch abandoned Fort Beversreede and dismantled and relocated Fort Nassau to the Christina River, downstream from the Swedes' Fort Christina. The Dutch consolidated their forces at the rebuilt fort, renamed Fort Casimir.[6] It was not until 1655 that control of the area was regained by the Dutch in a military expedition led by Director-General of New NetherlandPetrus Stuyvesant, establishing a regional capital at New Amstel.[7]
Site
There is no remnant of either Fort Beversreede or Fort Nya Korsholm. Nearby Mud Island became the site of Fort Mifflin in 1771. Widening of the Schuylkill's channel, subsequent land reclamation, as well as other transportation and industrial infrastructure have dramatically changed the area. But the site of the forts (whether on the east or west bank of the Schuylkill) is probably south of the mouth of Mingo Creek and north of the George C. Platt Bridge.[8]
