Drums from beacon tower deter people from moving;
邊秋一雁聲。
audible only at frontier in this autumn is a lone geese crying.
露從今夜白，
From tonight chilly dews will become heavy and white,
月是故鄉明。
but not as white as the moonbeams in my hometown lit.
有弟皆分散，
My brothers have all scattered and lost in nowhere,
無家問死生 。
and they are still live or dead that I am not aware.
寄書長不達，
My letters are absolutely unable to reach their hand,
况乃未休兵。
let alone that the calamities have yet come to an end.
Either http://www.iciba.com/have%20yet%20come%20to%20an%20end
or https://www.google.com/search?q=google+translate&cad=h
can check the validity of both expressions.
Both are grammatically correct and mean the same. 
Please read carefully my last reply again: 'I like your positive expression "have yet come to an end" much much .....' (There is only one "to" here. But there were two "to" in your original verse.)
I am not afraid to repeat it that the above positive expression is much more elegant and terse as well which one strives for in poems.
Further, to express negativity with positivity is always a triumph.
I like your positive expression "have yet come to an end" much much better，especially in a poem.
However, please note that there shouldn't be a "to" between "yet" and "come" as you put down. 筆誤 or 鍵盤誤？ 😄😄

I like these two lines. Your translation creates a new sense from the comparison!
