How did Howe's victory in Philadelphia change his strategy?

Howe's victory in Philadelphia shifted his strategy from a focus on conventional battles to consolidating control over key urban centers. By securing the city, he aimed to undermine colonial morale and support for the revolution, believing that capturing major cities would lead to a quicker resolution of the conflict. This change emphasized the importance of maintaining supply lines and establishing a strong foothold in the region, rather than pursuing further aggressive campaigns. Ultimately, it marked a transition toward a more defensive and occupation-focused approach.
