Unweighed cargo enabled theft beyond official detection. [causal]
Sea captains ordered to deliver the army's supplies of food and military equipment from the Egyptian ports of Suez and Quṣair to the Arabian port of Jedda complained of low pay and refused to undertake the job. The amount of food sent to Arabia, when it did arrive, was discovered to be insufficient and it was suspected that the sea captains might have been stealing from it. Since on being loaded in Quṣair, however, it was not weighed, it was impossible to ask them to make good the difference.
