From the Hans Christian Andersen biography "The Life of Hans Christian Andersen. Day By Day", written by DPhil Johan de Mylius:
1848Outbreak of the three year war
Christian VIII dies, Frederik VII is the new king. HCA is deeply affected by the death of the king.
HCA is, along with Oehlenschläger's son William, decorated as a knight of The Swedish Order of The North Star. He receives it on 25th February,
"The evening the king was buried [...] it is worn with a black band, and this was most important to me on this particular day; the colour will remind me of the grief associated with this day"
(draft for a letter dated 16th march to the hereditary Grand Duke of Weimar).
Oehlenschläger embraces HCA in congratulation and gives him his own miniature copy of the Knights' Cross of North Star (Oehlenschläger himself is a commander of The North Star at this time). HCA lost this miniature cross in 1862 in Malaga, along with all his other miniature orders. HCA also receives in this year the cross "Vom weissen Falken" (of the white falcon), 1st grade, from the hereditary Grand Duke of Weimar.
