Ports, and shit any infrastructure, specifically built and designed to export materials and goods from the colony.

"wow the Brits * gave* this country railroads!" yeah, but why is it a single rail, running from the port, to the mines, with no stops inbetween?

In the first few years of Nazi occupation in the Netherlands the Nazis took the rubber from everyone's bicycle tires, and people modified their tires with wood . Kids could then still ride them to school. I'd like to see you replace your horses broken leg with wood. Bikes were also modified to generate power for resistance printing presses and to light peoples houses during outages/Nazi mandated blackouts.

FWIW a little later on in the war the whole bicycle would be confiscated, either for the steel or taken by German soldiers who wanted to flee. It's the source of our national anti-German quip: "give us our bikes back".

Dutch Jews were never allowed to own bicycles.
