One thing to take note of right off the bat - you have no starting money and no income. Troops will still spawn but you do not get to add any additional forces/objects or call in artillery, which allows you to focus on the fight. Which is good for you, because if you're going to win this one you're going to have to fight hard!

You will deploy under the cover of night. Troops will move into position in the woods at the outskirts of town, drawing enemy fire. At the first light of dawn, the charge will commence. Make liberal use of your grenades to take out machine gun emplacements, artillery batteries, and barbed wire/other obstacles that may be blocking your troops way forward. The most crucial thing is to take and hold the trench line that runs through town during the first day. If you fail in this, it is unlikely you're going to succeed.

As night falls on the first day, your troops will regroup across the town and brace for the enemy counter attack. The two houses just outside of town have MGs and artillery batteries which will be crucial not only in this defense, but also in the offensive assault you will mount the next morning. Try to hold these houses throughout the night.

At first light of the next morning, any remaining enemy forces will begin retreating back to the far trench. Try and man all available mg's and artillery batteries to provide cover and weaken the enemy line as you send all remaining troops to capture the flag beyond the far trench before time runs out!
