This is the ditches a little closer up. We tried to make a little bit of the Low Countries with this table.
The figures are the French side, showing the Swiss and French Guards. Sometimes I count the ditches as a feature, others not.
In War of Three Kings we did count them as a terrain feature, so there were a lot of disrupted formations as we advanced. The rule was while part of the regiment was in the feature, the formation was disrupted, but reformed once they were on the flat. And they slowed movement.
