About this quiz

What this quiz covers

From the North Sea to the Atlantic, this quiz explores how submarines, mines, convoys, and surface fleets shaped World War I’s outcome. You’ll revisit key policies and turning points such as blockade strategy, neutral shipping disputes, and the escalation of submarine warfare.

Each question has 4 options and there’s no timer, so you can think through details like tonnage warfare, detection limits, and diplomatic consequences without rushing.

Skills you’ll practice

You’ll sharpen your ability to connect naval operations to wider wartime economics and politics, not just memorize dates. Expect a balanced mix of straightforward recall and “cause-and-effect” reasoning across mixed difficulty.

Identifying major naval powers, commanders, and theaters tied to U-boat operations
Understanding how blockades impacted industry, food supply, and morale
Recognizing key technologies (torpedoes, mines, hydrophones) and their limits
Linking unrestricted submarine warfare to diplomatic reactions and policy shifts
Distinguishing convoy tactics, anti-submarine measures, and their effectiveness

Common pitfalls (and how to avoid them)

Many players mix up WWI and WWII submarine concepts, or assume later technologies and doctrines already existed in 1914–1918. Another frequent trap is treating blockades as purely military events rather than long-term economic pressure with legal and diplomatic constraints.

Difficulty and length options

Difficulty is mixed by design, with easier foundation questions blended with tougher nuance so the challenge stays steady. Before you start, choose how many questions you want to answer and select a difficulty setting that matches your confidence—short sessions for quick practice or longer runs for full-topic coverage.
