Reading the wonderful book about sparrows "Mehr Platz für den Spatz!" Uwe Westphal.
I read this sentence "Angesichts der früheren Häuftigkeit der Vögel, die in teils riesigen Schwärmen über die Getreidefelder und Kornspeicher herfielen, konnten sie arme Kleinbauern durchaus in Existenznot bringen" Seite 96.
I had to look up the verb "herfallen über" in dict.cc. which means attack.
Could the verbs "attackieren" or "angreifen" had been used in this context?
Can the verb "herfallen über" meaning attack be used for people, armies etc ? Or used with larger animals such as lions, dogs ?
Is the verb "herfallen über" only used with smaller creatures like sparrows or mosquitoes attacking somebody or something?
What are synonyms of "herfallen über"?
