Which episode is about Axis Powers Hetalia Lithuanians saving Poland?

Among them, Axis Powers Hetalia's episodes are

1. The first sentence (World Congress, show one side)

2. Paragraph 47 (Negotiations with Britain/France/China)

3. Fifty-sixth sentence (dew bear attacks man's wife)

4. the fifty-seventh sentence (ibid.

5. sentence 69 (Finn/Lan's brain supplement shows one side.

6. The seventieth sentence (timid mode begins)

7. The eighty-third sentence (with a side at the beginning)

8. The ninety-fifth sentence (see wife's little XX=)

9. The ninety-sixth sentence (about the past history)

10. sentence 97 (playing chess with his wife before the end of the film, women's clothes appear)

1 1.EX02 Pseudo 102 (at first, I went to see bears with my wife and women's clothes appeared)

So I totally think it's episode 56.
