Chapter: The Army on the March 9.14
< /br>

When, in consequence of heavy rains up-country, a river which you wish to ford is swollen and flecked with foam, you must wait until it subsides.

When there are no bridges, roads lead to the wider and slower stretches of rivers which can then be crossed on foot.

It does not take much depth to sweep a man off his feet. A fast-flowing stream need only be about up to his knees. Hence, attempting to cross a swollen ford (and white flecks are a sure sign) would result in the loss of many soldiers.
