I am going to assume Az has the torch light source, He casts his spell, feeling the energy quicken his step, he moves forward to keep up with the party, though he could easily pass them by but considers that really foolish and dismisses it right away.
The rest of the party moves forward, cautiously awaiting the actions of the foes ahead of them, and as if on cue as soon as Kreeg see them with his darkvision, they (Two rows of goblins) see the party and open up a salvo of crude-looking javalins though none come close to hitting the party. They stand behind a crude barrier made up of assorded debris.
The humans see clearly until 'H' and vaguly see the stone bridge until 'L' then its inky blackness.
The Dwarf can see clearly to 'Q' and the two rows of goblins.
The Elves (and half elf) can see clearly intil "L" and can see shadows all the way to the back of the room, where you see a larger form barking orders...That just might be an Orc.
Actions?
Try to remember when giving movment I'd preferr coordinates 'P, ii' or 'L, iv'.
