On 20 January, Wavell visited Singapore to discuss the defence of the island with Percival. During this conference, it was decided that once the 18th Infantry Division had arrived in full force, it would be allocated to the sector on the island believed to be where the Japanese would land, as it would be the strongest formation available with fresh troops. Percival believed that this would be the northeast part of the island; Wavell disagreed stating it would be the northwest section of the island (where the Australians were to be deployed). However, he did not force the issue and allowed Percival to deploy his forces as he wished. Wigmore commented that Wavell conceded the point "on the ground that was the commander responsible for results and had long studied the problem."
