Sanadkii 1639-kii, Ferdinand wuxuu mar kale ku guuleystay inuu burburiyo qorshaha Franco-Dutch. Ciidamada badda ee Holland waxay ka adkaadeen ciidamo waaweyn oo Isbaanish ah dagaalkii Downs
, kana soo degay xeebta ingiriiska, laakin waxay ku guul dareesteen in ay ka hortagaan ciidanka ugu badan ee ay wataan, ku dhawaad 7,000 ilaa 10,500 oo askari, inay kasoo degaan Dunkirk. Inkastoo Ferdinand uu fashiliyey tallaabadii Amiirka Orange ee ka dhanka ahaa Hulst, ciidan Isbaanish ah oo uu hoggaaminayo Count Piccolomini ayaa burburiyay ciidankii ugu weynaa ee Faransiiska ee koonfurta ku jiray Dagaalkii Thionville.
