 This involved No.9 Commando of 2nd Commando Brigade and 24th Guards Brigade advancing up the flooded margins of Lake Comacchio in LVTs to concentrate near Chiesa del Bando, north west of Menate and develop a threat to Argenta which lay some to the south west of this objective.A foothold was established on the Fossa Marina, a canal running roughly east to west from Argenta to the lake and a short of their objective but then the newly arrived 15th Panzer Grenadier Regiment blocked further progress and an attempt to take the bridge across the Fossa on 14 April was beaten back.
