Map List


In 2015 on a sea map in the National archive of the  Netherlands a reference to a ship disaster dating to  1715 AD in Finland was discovered. The identification was simple only one Dutch ship  was reported to have sunk there in the period and that is Huis te Warmelo.

Dutch-Anglo fleet in the Baltic Sea area

On the 1st of June 1715 a Squadron of 12 ship of the Dutch admiralty was assigned to protected a merchant fleet of Oostvaerders that departed Texel for the Baltic sea. It was part of an combined Anglo-Dutch fleet to protect Dutch and English interests in the Baltic area.

The reason for the combined fleet was the ever growing tension between Russia and Sweden. Russia had built a new modern navy with much help from the Dutch Republic. Shipbuilding technique, ships and officers to man the newly built Russian fleet were provided by the Republic. Tsar Peter visited Holland twice to learn all about shipbuilding. The Swedes were attacking all Dutch and English merchants in the region as an answer. In the Sont the Dutch met with the English fleet of 20 ships under command of John Norris meet with the English fleet. The combined actions were a great success, very few incidents were reported and most Swedish privateers stayed in their home ports.

The Huis of Warmelo was one of the ships under command of rear admiral Veth who was cruising in the Finish gulf when she sank. This was the only major incident during the operation. Because of the great success the next year a new combined fleet was sent to the East Sea region.

Cornelis Cruys Dutch commander in the Russian navy

In 1697 after many years of domination by Dutch trade-activities, the maritime relations between Russia and the Netherlands changed and became more navy-minded. During the visit of the Russian Grand Embassy to the Netherlands, leading participants of this delegation, like admiral-general François Lefort and Tsar Peter, started to recruit shipwrights and seamen in Amsterdam for the Russian Navy. The tsar needed men for his war against the Ottoman Empire and his plans in the Baltic Sea. This war started when Peter the Great tried to conquer the Turkish fortress of Azov to get an entrance to the Sea of Azov and the Black Sea. His first campaign against Azov in 1695 failed, but his second attempt the next year led to victory*.

One of the Dutch marine officers who went to Russia was Cornelis Cruys born in Norway (1657) but living and working for the Amsterdam Admiralty in Amsterdam. His first commission was the buildup of the Azov fleet. In 1698 Cruys became commander of the naval wharf in Voronjez.

About ten years ago a wreck was discovered in Finish Gulf just outside Helsinki.
Until 2015 it was reffered to as the wooden cannon wreck. The structure is very well preserved and with cannons on deck. In 2015 a reference to a ship disaster was discovered from 1715 that mentions a Dutch ship in the Finnish gulf.
In the summer of 2016 and 2017 a team of Subzone has done research on the wreck.
