St Martin was first occupied by French freebooters in 1638, but ten years later the division between France and Holland was peaceably made.
Partly for the defence of the kingdoms and partly to overawe the freebooters and mosstroopers who were a perpetual menace to the peace until they were suppressed in the 17th century, castles were erected at various points on both sides of the border.
Freebooters trained in Territorial licence had a free hand on both sides.
In 1884 Mr Hofmeyr led the Bond in strongly supporting the Transvaal Boers who had invaded Bechuanaland (q.v.), proclaiming that if the Bechuanaland freebooters were not permitted to retain the territories they had seized, in total disregard of the terms of the conventions of 1881 and 1884, there would be rebellion among the Dutch of Cape Colony.
Fortunately, however, for the peace of Cape Colony at that time, Sir Charles Warren, sent by the imperial government to maintain British rights, removed the invading Boers from Stellaland and Goshen - two so-called republics set up by the Boer freebooters - in March 1885 and no rebellion occurred.
