O banks of the Rhine! We have seen you covered with gore, inasmuch as the swords of retribution were drawn against you; and you shall have another turn. And We hear the lamentations of Berlin, though she be today in conspicuous glory.

O banks of the Rhine!
In one of His Tablets written before the First World War (1914-1918), ‘Abdu’l-Bahá explained that Bahá’u’lláh’s reference to having seen the banks of the Rhine "covered with gore" related to the Franco-Prussian War (1870-1871), and that there was more suffering to come.
In God Passes By Shoghi Effendi states that the "oppressively severe treaty" that was imposed on Germany following its defeat in the First World War "provoked 'the lamentations of Berlin' which half a century before, had been ominously prophesied".
