De Vries opposed the governor's decision because he did not have the approbation of the Twelve Men. De Vries also declared that in 1630 they had already lost a colony in the South River at Swanendael on account of triffling with the indians and that thirty-two of his men had been killed and that ten years later more people had been murdered by the indians. That was the reason he opposed to attack the Algonquins.
