At about the 12 minute mark Ian Fleming explains to to March-Phillipps that the U-boats need "fuel and torpedoes, but they also need carbon dioxide filters, for oxygen."
U-boats didn't have CO2 filters. They had the air on board when they dived, which, along with the batteries supplying the electric motors they used when underwater, limited the time they could remain submerged. There were several instances of U-boats being forced to surface after long periods of being depth charged because their air supply had been exhausted.
This is an unnecessary mistake that didn't need adding, as simply taking out a ship being used to resupply U-boats is (and was, as Operation Postmaster actually happened) sufficient.
