Imperial Japanese military song - Imperial Army entry into a castle (皇軍入城)

This is a song about imperial army entering a castle/fortress, I'm not sure what 城 (castle) means in the context, it might be an analogue for a really fortified town or a bunker or something, this song is about glorifying IJA once they conquered the fortress. Translation may not be perfect because I'm not native Japanese.

Fun fact - As with the Chinese, the Japanese called themselves from Divine Continent (神州) as well. As with most of my songs, the translation won't be perfect because Japanese and English are massively different languages, with different structure, verbs and meanings; literally translation won't sound very good as well; I'm also not Japanese so my translation may be off context/meaning.
