Sapling homework

Hi guys,
Can anyone help me in moving arrows for Q.19 of sapling homework?
I am stuck with the final step where a base picks the hydrogen from benzene and the electrons from that bond forms the double bond. Is the base FeBr4 and how do you form HBr and FeBr3? The mechanism was not shown in the book but we   have to show it on sapling.

Thanks.

    Frank,

    I couldn't figure out how to insert a .JPEG file into a comment, so I've created a new post called, "Sapling Homework Hint - #19"
