The calculation was that the three columns would reach King's Bridge about the same time. Lincoln was to halt at Van Cortlandt's, Scott at Valentine's Hill, near the present South Yonkers Station, and Wooster at the top of the Williams' Bridge Hill. Wooster struck the enemy's pickets first at the top of the Williams' Bridge Hill, and pushing on, drove the enemy from the redoubt on the Claflin, or Perot farm, and the British commander of the fort at King's Bridge was ordered to surrender. The redoubt on the Bailey place, which commanded the fort at King's Bridge from the south and rear, was also taken possession of by the Americans, and tire was opened on the fort at King's Bridge. It was determined to carry this fort by assault.

The enemy cannonaded from the fort and killed one American as the guards were being relieved at

the Negro Fort.' A plan to cut off the battalion in the fort at King's Bridge, by putting a strong force over Spuyten Duyvil Creek on the ice, was matured. A thousand men were detailed for the i)urpose, but the weather growing warm, it was deemed too hazardous to risk the men on the ice the next morning. There was a heavy cannonading kept up all day, and the enemy on the island were thrown into great confusion. Heath observing that the British, during the cannonade, took refuge behind the hill at the bridge on the Hudson River side, rode around in the afternoon to Tippit's Hill, which was in the rear of the British position, though on the Westchester shore, and concluded that a field-piece placed there would leave the enemy no hiding-place. This was near the present residence of Mr. Edsall, at Spuyten Duyvil.
