The battle Germany cannot easily avoid

A German navy designed primarily to retake Helgoland would face a known battle space close to home. Battlecruisers would contribute less because Germany would not need high-speed scouts to discover where the enemy or objective was. Designers would instead debate heavily armoured battleships, amphibious shipping, large gun batteries, and numerous cheap flotilla craft able to isolate the island. Holtzendorff would probably clash with Tirpitz and Wilhelm over these priorities, sharpening the conflict inside the naval leadership. The procurement question becomes whether speed and global reach are worth more than armour, firepower, and the ability to endure a predictable coastal battle.
