Iambic pentameter....again!

[mountainboo]

Sorry, I still have a mental block where this is concerned and I have an A-Level exam on Monday which focuses on WW1 literature. From what I have read it can vary. How do I know if it a poem has iambic pentameter? I am aware it is something Shakespeare used a great deal but when analysing the following poem I read that it to has iambic pentameter:

Hooded in angry mist, the sun goes down:
Steel-gray the clouds roll out across the sea:
Is this a Kingdom? Then give Death the crown,
For here no emperor hath won, save He.

Can someone help please?

TIA

P.S The poem is by Herbert Asquith

The first line is not strictly iambic, as the word 'hooded' has the stress on the first - not the second - syllable. Apart from that, the lines ARE iambic and - since each line contains FIVE feet - they are pentameter also.
Just ask yourself if the rhythm of the lines is:
ti-TUM, ti-TUM, ti-TUM, ti-TUM, ti-TUM
with 'ti' representing an unstressed syllable and 'TUM' representing a stressed syllable.
