gunboat

Rereading the text of yesterday .This passage made me try and find out once more about ship and captain.
Silliman says - our packet was called the Johanna Wilhelmina (Captain Vlieland.)

=This very packet was built for a gun-boat for the invasion of England ; she was taken in action by the English, purchased of them by a Dutch captain, and converted into a packet to sail between Rotterdam and London. She was however, in every respect inferior to the American gunboats., except that she was deeper in the hold, but, still we could not any where stand upright.=

Back to our gunboat in Dutch kanonneerboot.

Not many gunboats were auctioned of .

These are the only ones to be found in the newspapers.

1801

In 1805 we find

which means .
The ship Johanna Wilhelmina last sailed by captain A Vlieland will be sold on 12 March 1805 Rotterdam.

More about the Johanna Wilhelmina
and the passage to Rotterdam .
Lloyds registers 
and more about the Wilhelmina which is probably the same ship.

There was even a gunboatwar during the Napoleontic war .
