Retaltion/Block question

Quick question and hopefully simple. I cant get a solid test down to see if this works or not, but does retaliation damage trigger ON SHIELD BLOCK. AKA if I block an attack with my shield, will a creature still be dealt retaliation damage?

Yes retaliation triggers on block.

To be crystal clear : retaliation triggers each time you are hit in melee range, no matter if you succeed in blocking or not.
