I was watching a show on the American war of independence, and saw battles between the American and British forces being fought in this way. Many battles in that era seem to have been fought with this weird protocol where the two sides stood in rows and patiently loaded their guns taking turns shooting at each other.

我正在看一檔關于美國獨立戰爭的節目,看到美國和不列顛軍隊之間的戰爭就是這種方式。那個時代的很多戰爭似乎都是以這種奇怪的規則進行的,雙方站成一排,耐心地裝槍,輪流向對方射擊。

why would anybody agree to this way of fighting? Were there instances of the fighting starting out this way, but ending in a free-for-all?

為什么會有人同意這種戰斗方式?有沒有這樣的例子:以這樣子開打,最后卻打成混戰?
