I think Bruma was quite possibly the only city not attacked. It's not explicitly stated, but Bruma would likely have been the route used for Titus II's escape to Skyrim prior to the sacking of the Imperial City as well as the subsequent return to Cyrodiil with the combined forces of the Nord legions under General Jonna.

Skingrad must have been taken by the Aldmeri as it was one of the points they counter-attacked from as Jonna's men moved west on the Red Ring Road.

I would guess that Murky Night is right about Chorrol and Cheydinhal, although they may never have been attacked at all. Certainly by 175 both cities must have been under Imperial control, or at least not under Aldmeri control, for the Imperial attack to have remained a surprise to Lord Naarifin and the Aldmeri who counter-attacked Jonna's troops.
