Why more troops would not automatically solve the Levant campaign

Steve's proposal emphasizes transferring trained men and finding more suitable horses locally. The objection is that the region already struggled to support the troops it had. Supplying the advance by sea would also need appropriate shipping, and the discussion says warships were being used despite their poor suitability as cargo carriers. Coastal supply could not by itself reach every important inland objective. Ottoman railways offered a way to move troops and stores through the interior. The debate therefore turns from troop numbers to how the campaign could be sustained.
