Paul Hollywood looks into his family's past this week. His journey takes him first to North Africa where his grandfather had only just completed his training when he found himself in Tunisia as part of the Light Anti-Aircraft division tasked with protecting infantry from enemy air attack during a major Allied offensive to take Tunis from the Germans. He then makes his way to Italy where he learns his grandfather was part of the landing force that became surrounded by German forces and trapped on the beaches at Anzio for four months.
