[1] Whilst in Baghdad he learnt of the exploits of four European generals, Jean-François Allard, Paolo Avitabile, Claude Auguste Court and Jean-Baptiste Ventura who had thrived in the service of Maharajah Ranjit Singh.

[3] In Lahore, he initially treated East India Company soldiers before he was able to attract the attention of the Ranjit Singh who made him a court physician.

Ranjit Singh offered him command of an artillery battalion, but Honigberger refused on want of not being a soldier, eventually however he accepted an appointment as superintendent of the royal gunpowder factory.

[8] In 1839 Honigberger was present at the funeral of Ranjit Singh, a ceremony he described as abominable, and of which he wrote a detailed account of the burning of four of his widows, and seven concubines.

He became a student of homeopathy and is said to be responsible for its introduction to Asia, notably using homeopathic remedies to cure the Maharajah's paralysed vocal chords.
