The vast majority of breads are high GI. There are some of the rye ones that are a bit kinder, but 125g odd of bread will spike most people quite badly. A lot of folks would say you were lucky to get away with being in single figures at the two hour point with that kind of amount

The French stuff is a killer (or at least most of the French styled breads over here are). What kind did you go for?
Soup. Well, the more you blend something, the less work your digestive system has to do to break it down and the faster it will spike you. That's why 30g of carbs in an apple will raise your BG more gently than 30g of carbs from apple juice. Unless it was a really chunky soup, those carbs would have been pretty quick as well. No matter, the main culprit was the bread IMO.
I love bread, and do sometimes eat a lot in one go but I know that it has the potential to bite back. And I consider that I tollerate bread pretty well in the great scheme of things.
Soup and a hot shower. You students know how to live....

And then a little pump floats by
And now my pants are filled with tubes
That tangle all around my.... er .... knees
The hours I'm hooked up? All twenty four
And that's it for now until evermore
But I disconnect for up to an hour
For wonderful fun (and sometimes a shower)
And when I 'suspend' it, it plays Barry White
And my wife knows she's in for one heck of a night
But only an hour of that night is with me
As an hour is all I'm allowed now, you see...
