I can't find the battle that trenches were especially useful in, but pretty much, trenches would be used to slow  enemy infantry and cavalry charges while longbow-men would pick them off with arrows. Especially in rainy semi-coastal areas, were it was muddy, men could get stuck and even die in trenches.

Another use was to conceal your true numbers, conditions, and hide from arrows and missiles. You said yourself. Slow them down. They'd don't actually do any real harm…
