The others are right, this is the correct translation.
The Zeeuwsch Legioen was set up on 1 March 1807, and was to consist of the 3 battalions of the 5th Infantry regiment, with 3 added artillery companies.
The 2nd and 3rd battalions of the Legioen were to be recruited exclusively from Zeeland natives, and were not to serve outside of Zeeland.
On 21 March 1807, a new 5th Infantry Regiment was raised, which could serve anywhere.

As far as I know, due to the fact that the Zeeuwsch Legioen was wiped out during the Walcheren Expedition, the 'new' 5th Infantry regiment was once again converted to be the Zeeuwsch Legioen in 1809
