A huge crash at the start of the Belgian F1 car took out championship leader, Fernando Alonso.
Romain Grosjean cut across the track, hitting Lewis Hamilton and forcing him wide on to the grass. The McLaren driver spun as he smashed into Grosjean, who then hit Alonso and Sergio Perez.
The safety car was deployed to clear the debris and Lap 5 saw it come in as the drivers finally got back to racing. Pole-sitter Jenson Button led the pack up to Eau Rouge with Kimi Raikkonen and Nico Hulkenberg following behind.
Pastor Maldonado, despite an obvious jump-start brought out a yellow as he pulled off track at Les Combes with a front wing missing.
Taking part in his 300th Grand Prix, Michael Schumacher took advantage of the first lap carnage to get up to 4th, after qualifying in 13th.
A battle between the Red Bull drivers saw Sebastian Vettel overtake Mark Webber at the final chicane, as the German also looked to improve on his terrible qualifying position.
Lap 12 saw the start of the first pitstops but Button had drawn out a 6.9 second lead over Hulkenberg, and Schumacher was also flying and closing in on his fellow German.
There was drama in the pitlane as the Caterham of Heikki Kovalainen was unsafely released into the path of an HRT. And when race leader, Button pitted, his stop was an incredible 2.6 seconds.
With 14 laps remaining Button was leading by 15 seconds having had a quiet race, as Vettel and Schumacher trailed behind, followed closely by Raikkonen. The Finn eventually got past the Mercedes driver at the Bus Stop, while Narain Karthikeyan crashed out from last place in the HRT.
Multiple Spa race-winner, Schumacher used DRS down the straight at Les Combes to get past Raikkonen to take back third, but a lock up at La Source saw the Lotus all over the back of him and the Finn retook the position with a stunning overtake around the outside going into Eau Rouge.
A few laps later and Schumacher enters the pits as he was on a two-stop strategy, ruling him out of a podium finish.
Jenson Button took his second win of the season as he dominated from start to finish in a perfect race. The action returns next week at Monza for the Italian Grand Prix.
