[1] Hackius succeeded Jacob Borghorst as commander on 25 March 1670 and was appointed to a position similar to governor on 2 June 1670.
In 1656 he returned to the Netherlands and thirteen years later, in 1669, he was appointed head of the refreshment station at the Cape.
When Isbrand Goske visited the Cape in February 1671, he was very critical of Hackius as many assignments had not been carried out.
Hackius served as commander for only a year and eight months and his health deteriorated rapidly, and the secundes, Hendrik Crudop and Cornelis de Cretzer had to handle the administration.
[3] During his reign, efforts were made to encourage immigration from Holland, but nothing of importance really happened.
