 Now all this caused delays in the march and that threatened to ruin Washington's plans. You see, he had hoped to remain concealed under the cover of darkness and to arrive at Trenton prior to sunrise so that they could catch the Hessians unprepared.

Perhaps the weather being so bad would provide his army with the cover it needed.
