A bombardment is an attack on a place that does not stop for a while: big guns and bombs, again and again, not one blast and then silence. Cities, forts, and positions come under bombardment. The word is at home in war news and history, and it feels serious. People also stretch it: a bombardment of questions, ads, emails, photos. Then it means so many things hit you that it feels like an attack. That stretched use is common and a bit looser; the war use stays the core. One bomb is not a bombardment. The long, heavy rain of attacks is.
