Political, etc
Austria-Hungary: Emperor Charles and Czernin letter to Kaiser Wilhelm II, ‘
Five monarchs have been dethroned in this war…’ warns of Russian Revolution impact.
Germany: One of the worst outright lies perpetrated by British propaganda first makes its way into print. Berlin Lokal Anzeiger‘s corpse conversion factory story (first appears in Belgian newspaper) becomes war’s most notorious atrocity story (not exposed till 1925). Balfour writes on April 26 that it might be true.
