1. We begin a blockade of the ocean leading to France, preventing Swedish interference from messing with our grand plan. The English Channel is mined and blockaded, making travel very difficult. 2. Sending generals to the Commune of France, we help organize the rebel forces. We instruct them to form a massive link between their forces. This link is not a massive wall, but a field of intense guerrilla warfare, pillboxes, landmines, traps, dense forests, and partisan sabotage. The activity here is so intense it is almost impossible for French troops to pass through the links between the rebel territory. 3. We launch an invasion with 80,000 men from the north, heading for Paris. This will cause the French to panic, because the government's main point so far is that they won't surrender since Paris hasn't fallen yet. However, this is simply a distraction. 4. From the south, 1,500,000 troops surge-veterans, recruits, all of them all at once. We shatter through French lines with motorized infantry and heavy tanks. When the French retreat, their exit will be blocked off by the rebel partisan link in step 2, the piece de resistance of our master plan. Unable to escape, we will force their entire army to surrender. If they do not, our heavy artillery will bombard them into submission. 5. We leave a garrison force of 200,000 in the territories, since we don't want the pesky Swedes to land an invasion force while we aren't paying attention.
This might be the final offensive of the war, depending on how well this goes.
