Phase 7cJ2B is the period of the fist Mittani deposits in J2. During this phase a small curtain wall was built parallel to the revetment wall. It was presumably designed to screen off the revetment wall and protect it. The wall cuts through some earlier (EDIII) materials and so is dated to the early Mittani.
The construction of the wall indicates that the area continued to be used in the Mittani period before it was covered by the brickfall (see Phase 7jJ2B). There are no floors or other use associated with this construction, and it is therefore assumed that any materials from this period were eroded during the subsequent phases, particularly at the beginning of Phase 7jJ2B.
