What happens to the Wostertoren bells and how does Anne feel about it?

they were seized for factory use, and melted down into weapons

Explanation:

A year later, the bells of Amsterdam’s beloved carillon fell silent. Anne speculates they’ve been seized for what she sarcastically calls “factory use” in her diary. She fears they’ve been confiscated by the occupying Germans, as many bells were during the war, to be melted down into weapons.
