Why did DeVries oppose the governor's plan to attack the Algonquins?

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.
