Hello! For my lab report I need to draw the Mechanism of synthesis of E-stilbene, and though I get some of it, my class is significantly behind the lab, so I have no idea what to do next!

I know that when we add benzylmagnesium bromide and benzaldehyde to each-other, conjugate base 1,2-Diphenylethanol is formed (https://www.chemspider.com/Chemical-Structure.84992.html?rid=11c9ece0-87e5-47b0-8dc5-a047b36ec6f1). However, then we add HCl to it and E-stilbene is supposed to be formed already, and what's the mechanism of it? I have no clue! This is is just incredibly frustrating...

Also, if you are so kind, could you please tell me what are the side-products of this mechanism are?
