It took the army nearly two days to reach Saratoga, in which heavy rain and American probes against the column slowed the army's pace. Burgoyne was aided by logistical problems in the American camp, where the army's ability to move forward was hampered by delays in bringing forward and issuing rations. However, Gates did order detachments to take positions on the east side of the Hudson to oppose any attempted crossings. By the morning of October 13 Burgoyne's army was completely surrounded, so his council voted to open negotiations. Terms were agreed on October 16 that Burgoyne insisted on calling a "convention" rather than a capitulation.
