The flower was given by local womens, as stated here no one in France wanted to go to war, due to the stigmatas of WW1. The flower was probably an act of kindness to help ease the pain. Hell ... doesn't take a genius to figure out how u'll feel if u were draged away from your house, given 5 bullets and an old gun, and asked to go "fight" up north.
My GF ended up runing for a week, scavaging on what he could find till he met with a "Chasseur Alpin" unit. Spent the rest of the war playing hide & seek with the Germans, ambushing in the mountains. Made a erman officer prisoner at the end of the war ... while runing away, the German officer was runing too, they bumped into each other in a corner, my GF drew his gun first.
My other GF was in the resistance, ended up being captured, tortured and deported. Survived the "work camp", ended up being exchanged.
His brother wasn't so lucky, he ended up burning alive in a French tank that was set on fire by a German flamthrower. The crew was locked in and couldn't escape as the French officers lokced them up in so they had to fight to the death.
Sucky war for the French the BOF, far from the glorious D day stories.
