Question: When did US ground forces attack Iraqi positions?
Sentence: Over 6 weeks of relentless pounding by planes and helicopters, the Iraqi army was almost completely beaten but did not retreat, under orders from Iraqi President Saddam Hussein, and by the time the ground forces invaded on 24 February, many Iraqi troops quickly surrendered to forces much smaller than their own; in one instance, Iraqi forces attempted to surrender to a television camera crew that was advancing with coalition forces.
Answer in sentence: yes
