The 1618 Prague defenestration took place on May 23th, 1618 and OΓ±ate's news about it arrived to Madrid in July 1618. This is compatible with the duration of the communication to be 5-7 weeks which is absolutely reasonable. 200,000 ducats were immediately reserved to beat the courageous Czechs and additional 500,000 ducates were sent in November.
The distance between Prague and Madrid is some 1800 kilometers by air. The actual route could have been substantially longer, perhaps 2500 kilometers, and Alps are in between. 40 days of transmission of the signal is absolutely reasonable without any electromagnetic communication β some 60 km per day.

In the Middle Ages and in the early modern era, theoreticaly the message could have reached 100-150 km per day, once there was a good network of postal stations and the horses and messengers were changed. The message could have travelled also by ship and in that case, it took even less time. Naturaly, people normaly travelled ca. 25-30 km per day, but the armies were not sent directly from Spain, but from Netherlands, or Italy, or they were just hired for Spanish ducates that could have been transfered via message.
