== Casualties == 

 Sir, 

 The description of the Battle of Bang Bo (Zhennan Pass) does not fit with the one given in the article on Feng Zicai - note that the latter article does not include any reference, but may have been influenced by the prolific and highly unreliable Mitch Williamson 1884-1885 Franco-Chinese War.  

 The numbers given in the paragraph “casualties” in  Battle of Bang Bo (Zhennan Pass) (146 killed in the five units mentioned) do not tally with the number of casualties on the French side at the top (74 killed, less than the 79 killed in Verdier’s brigade - see Harmant 1892 p.235). Moreover, on 21 August 2009, anonymous "66.108.141.251" has still reduced without any explanation the number to 63 (and other figures as well). I did not revert it because the original figure seems wrong. 

 More generally, are you sure the numbers of casualties you provide for "the French" include those of Vietnamese units under French command?
