The opening line of the poem is the first line of the poem, which is called the first verse.
<h3>What is a verse?</h3>
Although verse refers to a single poetic line, the term is increasingly used to refer to the poetic form in general. Formally, a verse is a single metrical line in a poetry poem.
Verse, on the other hand, has come to denote any grouping of lines in poetic writing, with groupings generally referred to as stanzas. In contrast to prose, verse in the uncountable (mass noun) sense refers to poetry.
Therefore, the first line of the poem, known as the first verse, is the poem's opening line.

Explanation:
Historically speaking, rivers had a monumental impact on trade, transportation, and natural resources in all regions of the world prior to the development of turnpikes and locomotives. The ancient Romans used rivers for their plumbing and water systems, the Egyptians used the Nile river for trade and for water supply for their crops (and still do), the United States used the Mississippi river to access their northern and southern regions must faster to transport soldiers and commerce in and around the country. Until the "era of the railroad," water passageways were essential to the success of any economy.
World War I completely changed the way wars were fought.
Trench warfare, which was the norm just a century ago was seen as an nonviable strategy.
Modern machines such as tanks and airplanes made trench warfare mostly about keeping ground and resulted in stalemates.
Also, it was the first time that modern tanks, planes and machine guns were being used for first time at such a large scale, resulting in an unprecedented level of death and carnage.
Military generals soon realized that time-honored military code of conducts were now obsolete and a completely new form of strategy was now required.
