When Councillor of India, Zwaardecroon was commissioned by the Government of India to compile a descriptive account of Malabar and Coromandel, a work which he appears to have satisfactorily accomplished. During his Governor-Generalship he undertook for the first time, in 1723, the planting of coffee within the territories under his rule. For his exceptional services to the Company in introducing coffee and the silk worm industry into Java he was much commended by the Directors of the East India Company, and was presented by them with a silver tankard inlaid with gold, bearing a suitable inscription on the lid.

Of his marriage and descendants I have not been able to obtain any definite information. He appears to have married in Batavia, but the lady's name does not occur. By this marriage he had two children: a daughter Hillegonda, who married Cornelis van Berendrecht, "waterfiskal" of Netherlands India, and a son, Hendrick Zwaardecroon, who is mentioned in 1703.
For the Instruction of the Honourable the Political Council of Jaffnapatam, compiled and left by Commandeur Hendrick Zwaardecroon on his departure from that kingdom as Commissioner for the Coast of Mallabaar, Cannara, and Wingirula.
It has pleased His Excellency Mr. Willem van Outhoorn, Governor-General, and the Honourable the Government of India, to appoint me Commissioner for the Coast of Mallabaar, and to require me to compile before my departure from here a Memoir or Instructions for the guidance of the Council, stating therein how the affairs of the Company are to be conducted during my absence, which Memoir is to be handed to the said Council after having been submitted to His Excellency the Governor of Ceylon and the Council of Colombo for revision, amplification, and alteration where necessary, as may be seen from the letter of May 23 last, from Their Excellencies at Batavia, sent here by the ship "De stad Leyden."
In compliance with this esteemed order I compile this Paper, although I am aware that you are all persons who have served the Company for a greater or smaller number of years, and that you must have had ample opportunity to obtain a knowledge of all matters concerning the Company.
Moreover, during the last 38 years which the Company has been in the absolute possession of this territory, many papers have been written with regard to Jaffnapatam which are always accessible to the members of the Political Council at the Secretariate, so that I take it for granted that, in addition to your daily experience, you have obtained a sufficient knowledge of these matters from these documents; because among these are to be found descriptions of whatever is necessary to give the reader a clear idea of all that is required in the Company's service, and they having been written by wise and circumspect men, some more and others less in detail. I am, therefore, sure that everything that is necessary will be found if carefully looked for.
