Well... To be fair, Manbij was taken from ISIL by SDF forces last summer, with some US aid.

Apparently the fighting was intense:

U.S. Army Colonel Christopher Garver, chief spokesman for the US military command in Iraq and Syria, commented that fighting was "very intense", describing it as "different than what we've seen in Fallujah [or] Ramadi" and concluding that "this is a fight like we haven't seen before."
