While it was unusual at that time for a British soldier in India to be a Cambridge graduate, William further differed from the norm by enjoying classical literature for relaxation. He was a keen linguist and had an interest in learning the main languages of his host country at that time. On his arrival in India he started first learning Hindustani and later Persian, with help and encouragement from his mentor, Sir Henry Lawrence. This apparently was of intellectual and cultural interest to him, particularly as his army quarters offered him little in the way of culture or reading matter, save for the "usual copy of the Bible and works of Shakespeare". He even asked for "a formidable collection of classics" from his brother, although he probably did not see anything unusual in spending three hours a day studying Persian. He even "found it relaxing to read untranslated Xenophon".
