美国两位历史学家Thomas Lowry 和 Edward Milligan 从国家档案发现至少至少51名华人参加了这场战争，甚至战死沙场。

Lowry said that although the number of Chinese who served was small in relationship to the total Chinese American population of the time, a higher percentage served than in any other ethnic group. He called for a plaque or a monument, to give credit to these men and to their brave and loyal service.

51人尽管人数不足为道，但是按照华人在美国的比例是个族裔里最高的！
