Germany had won an area called alsace-lorraine forty years before the outbreak of hostilities during world war i. which nation did they win this region from?

It was the nation of "France" that the Germans initially won this territory from, although it should be noted that this was a highly contested "land-grab" and many French disagreed about the specific borders. 

They weaken the south vietnamese army.
