Uhhh... No. During Charles VIII invasion of Italy, in 1494-1495, the sieges were solved in a matter of hours. The medieval walls were simply demolished by his artillery. The star fortress had been devised as a direct response to that threat, and the first purpose of bastions and rivelins was to not give to cannonballs directed towards the inner fortress a 90° impact surface. They proved to be so effective that practically the only way to conquer a star fortress, from then on, became to mine it.

Uhhh... No. Star fortresses did born as a direct response to Charles VIII invasion of Italy in 1494-1495, and, due to their effectiveness were already well diffused in mid 1500. The 30 year war started in 1618.

In reality what made bastion forts vulnerable had been explosive shells AND long-range howitzers, that allowed to send explosive grenades INTO the fortress bypassing the walls entirely.

What impressed western Europe the most was Charles VIII Italian expedition of 1494-1495. Previously, in Italian warfare, sieges lasted weeks and months (also giving the defenders time to negotiate) but, thanks to the new field artillery, the medieval walls were breached in a matter of hours, then the French, despite the easy win, applied "siege warfare rules" (due to the siege being usually overly costly for the attacker, if the defenders surrendered before the siege begun, they would have had their livese spared but, if the fortress/city was conquered, there would have been no pity for the defenders/citizens). Viewing the early examples, most fortresses and cities chose to surrender without a fight. That was stopped for the firtst time in the siege of Pisa, against the combined French-Florentine army in 1500. Again, the medieval walls were breached in a pair of hours, but the ditch and rampart the Pisans built behind the walls resisted for weeks, untli the French lifted the siege.

OK for the joke, but, seriously, Vauban devised the perfect tactic to lay siege to any star fortress, but it was not rapid. Unless there was some serious defect in the contruction (IE there were defects in the defenses of the city of Maastricht that, under the direction of Vauban, fell in 13 days, but that required anyway the work of 20.000 men digging trenches). That served the purpose of the fortress. Infact that it had never been to resist indefinitely, but to be extremely expensive to conquer.
