The best example of this is the NATO intervention in Yugoslavia over Kosovo. It was strictly an air campaign.
That's not quite true, there was an
organized land push from Albania in early April. KLA force of about 6.000 backed by Albanian army and NATO SF commandos tried to push into Yugoslavia in the region of Kosare, but were held there by a small border force of the Yugoslav army. One could argue that these weren't NATO soldiers on the ground fighting this battle, but it's a fact that NATO was using KLA as its infantry, or should I say cannon fodder, on the ground.
As for your other claims, that NATO was shocked by Milosevic's offer for peace, that also not quite true. First of all, while planing the aggression against Yugoslavia in 1998, NATO expected it would last only a couple of days, a week at most. Who could blame them, after all they sent almost 1.000 military aircraft vs only a couple of yugoslav Mig-29s who had some serious malfunctions. So yes they were shocked, shocked that it took 78 days of non-stop bombing, to make Milosevic ask for peace. And he did that only after NATO started bombing civilian targets such as hospitals, water proccessing plants, bridges, schools, car factories, and even apartmant blocks and civilian houses, because of their frustration of not being able to do any serious damage to the Yugo army on the ground, which ended the war almost completly unscratched.
