The reference to Flanders fields borrows a bit heavily from John McCrae’s famous poem–maybe she should have footnoted it:

In Flanders fields the poppies blow
Between the crosses, row on row,
That mark our place; . . .

And for an American, Flanders is probably the wrong place–not that there’s a “right” place to die in a senseless war–but very few Americans fought (or died) alongside the British in Flanders. Most were down with the French in Champagne.

However, there is an American military cemetery in Flanders, which covers six acres and includes 368 graves (two of the men buried there are from Utah and four from Idaho–so, maybe Mrs. Nelson knew one of them). By contrast, the Meuse-Argonne American cemetery, near the site of the heaviest fighting by U.S. troops, covers 130 acres and has 14,246 graves.

New Family Search says that’s Sarah Ahlstrom Nelson, and the Mormon Literature Database confirms that.

She doesn’t seem to have lost any children in the war, and neither did any of her siblings or in-laws (if New Family Search can be believed), confirming what I read as a slightly academic flavor to this poem, rather than addressing personal experience.
