What made the crossing of the Delaware river so difficult?

The crossing of the Delaware River was challenging due to harsh winter conditions, including freezing temperatures and ice floes that obstructed the river. Additionally, the soldiers faced logistical issues, such as limited supplies and inadequate boats for transport. The darkness of night added to the difficulty, as visibility was poor and navigation was treacherous. These factors combined to make the operation both perilous and demanding for the troops involved.
