In page Martin of Tours:

"

With the government's relocation to Tours during the Franco-Prussian War, 1870, numerous pilgrims traveled to St. Martin's tomb. The banner read "Heart of Jesus Save France" and on the reverse side Carmelite nuns of Tours embroidered "Saint Martin Protect France".[3] As the French army was victorious in Patay, some attributed it to Martin's intercession.[citation needed] Popular hymns of the 1870s developed the theme of national protection under the cover of Martin's cloak, the "first flag of France."[2]
