Specific numbers? No. It just says that the Rose Queen is on a mission to track us down along with an "entourage of the Summer Court's greatest warriors". And as for their movements... It's pretty explicitly stated that they became aware that the Rose was out of the Prince's grasp the moment that Steven tried to communicate with it. The Rose was stolen from the Rose Queen by the Prince himself, so it was really just a matter of returning to his realm to and seeing the destruction we left behind to put the pieces all together.
