1904

1 June 1904: Although it was uncertain whether the Royal Netherlands Navy would buy a submarine, the Dutch shipyard K.M. De Schelde in Vlissingen laid down the Luctor et Emergo. It was a Holland 7P type boat, designed by the Holland Torpedo Boat Co. Many sources report the type as Holland IX, but this is incorrect. This American company sent the engineer Ir. Marly Hai to the Netherlands to assist the Dutch shipyard during the construction of Luctor et Emergo.

3 Dec 1905: Luctor et Emergo is towed from Vlissingen to Den Helder via the inland route (canals) by the tugboat Jacob, they are accompanied by the a lighter. Due to a few collisions and other problems it takes them more than a week to reach Den Helder.

The trials in Den Helder are unsuccessful, the committee overseeing trials is not satisfied, and therefore the Luctor et Emergo returns to Vlissingen.

The Luctor et Emergo, still moored in Vlissingen, is frequently visited by Ltz. I  who still thinks the boat can meet the demands of the committee (see 25 Oct). Koster takes leave from the Navy and is hired by the shipyard K.M. De Schelde. P. Koster trains a handpicked crew and conducts new trials with the Luctor et Emergo.
