这个说法来自英语维基:
When Blue was less than 2 kilometres (1 mi) away from Mikawa's force, she suddenly reversed course, having reached the end of her patrol track, and steamed away, apparently oblivious to the long column of large Japanese ships sailing by her. [10]:171–3

下面是这本书相应的部分,并没有直接说明最近的距离是2公里,这个数字估计是从图上读出来的,但是这个图中日方航迹不准确,而且USS Blue的航迹也和原始报告不符。
