The garrisons of Lilybaeum and Drepanaand Hamilcar's army at Eryxheld fast, but without supplies from Carthage they could not hold out indefinitely. Carthage began to ready a fleet, fit out transports, gather supplies and train crews and marines to meet the Roman challenge. It took nine months to ready 250 warships and between 150 and 350 transports. Carthage was pressed for time as supplies in their blockaded strongholds were running out. They struggled to find the 100,000 men necessary to fully crew just the warships, and did not have sufficient time to provide the extended training necessary for the crews to work together effectively as teams.
