Although the city of Amersfoort in the province of Utrecht was captured, the Dutch did not give up their siege of Den Bosch, which meant that the main objective of the invading troops was not achieved.

In April 1629, Frederick Henry, the then Prince of Orange began his siege of 's-Hertogenbosch after the Spanish tried to start a blockade of the Dutch Republic in order to weaken its position.

In July the Spanish troops marched to Veghel through Boxtel, which meant that a siege of Grave was possible, Frederick Henry however saw no threat of the city being besieged since the garrison of the defended town was raised to 4.000 men.

[2] To further prevent this, the States of Holland decided to raise an army that consisted of 5.000 Burghers and Groningen and Frisia ordered the recruitment of 3.000 waardgelders.

And under the command of Jacinto de Velasco y Henin, the Count of Salazar, the Imperial-Spanish armies would attack Hattem which would open Frisia to an invasion.

[8] The Imperial-Spanish attack on Hattem failed, and the armies matched towards Oldebroek to plunder the city and threaten Elburg in the process.

The capture of Amersfoort caused great panic among the population in Utrecht, the city did not have the confidence that a garrison of 3.000 men can defend an assault.

Just before the invading troops retreated from the Veluwe, Frederick Henry of Orange captured Den Bosch, bringing his costly siege to an end.
