I had to Google Hautes, just to find out where it is. It helps if you could provide a Google maps link.
If you are looking for directions, places to see, great roads, please consider supplying the following basic information:
You have reserved three days to get from Holland to the Pyrenees, on good roads and to see sites.
Do you want to see things on your return ride, too?
if so, how long have you reserved to make the return journey, Hautes to Holland?
The majority of British WW1 sites are in the main to the north east or eastern side of upper France. The main WW2 sites are to the NW (Normandy) or the general Ardennes area, roughly NE, closer to Belgium. Trecking to Normandy is possible, but it very much depends on the answer to the two questions above and a part to some below. Look at a map.
You could also consider the WW2 'V-weapons' sites, in the Pas-de-Calais (NE France, conveniently).
Someone is bound to suggest Oradour for a WW2 site, they always do. This is roughly mid-way down the western side of France. Possible to do too, but again it depends on the answers to the questions. Again, look at a map.
More questions?
Yup, here they are:
Do you think 200 miles in a day is a long way? Some bods do and why not. France is a big country, so consider your honest answer carefully.
Do you want to start at 10:00 AM, stop to take pictures / press wild flowers / have coffee, kick off the shoes at lunchtime and be sitting in the bar by 16:00 at the latest?
Are you prepared to forego some 'great roads' for a motorway, if it means you could see a WW1 / WW2 site, too and still make it to Hautes inside three days?
Accommodation hints? Not much use if those suggested do not match in with where you need to be.
Have you got a decent map or two or are you relying on a PC and a Garmin or, worse, a TomTom?

My honest suggestion.
You can do much of this yourself and it is quite fun. A lot of what you need to know is already on UKGSer or on the internet. OK, you may need to do some mixing and matching. It's called a vague plan, if your current idea is not already vague enough
Arm yourself with a decent map or two (see sticky). Put a pin in the port and another in Hautes. Now divide the distance between the two points into thirds, 1/3 for each day for the sake of this exercise and now look at the scale.
Can you ride each third in a day and still see something and do great roads? If so, you are starting to cook on gas... which is good!
Are there any sites that you want to see (or indeed any at all) on any of the three legs, which will still leave you time to get each leg competed and get to Hautes, in order to do whatever it is you plan to do in Hautes?
The 'best' ones may well be the V-weapon sites mentioned above. I might be tempted to do one of them; half a day (or the better part of a morning or afternoon) so you are now down to two and a half days. Stop at another site, too? Another half a day vanishes and you now have two days. You get the picture....
PS The Michelin route planning map (see sticky) will be your real friend. Trust me. Pick out many of the roads shown on the map. You will not go far wrong.
I didn't think it could be done - 3 days to the Pyrenees AND visit battle sites. I certainly couldn't do it on A roads. The suggestion of sites pre WW1 & WW2 is good too. A refreshing change to all the usual sites - moving as they can be when the weather is poor and you are alone, they become a little Disney-esque in the sunshine and with millions milling about. There are also some great books about for pre-visit reading. I recommend 'Azincourt' by Bernard Cornwell for a starter.
