Judging the Regia Marina's convoy war

Was the Regia Marina successful at protecting North African convoys?

Largely yes in a difficult convoy war, though Britain had more strategic routing options and better opportunities to interdict Italian supply traffic.

Judging either navy in isolation obscures a Mediterranean campaign built around convoy warfare. Both sides recorded successes and failures, and many Regia Marina convoy-protection achievements merit the same standard applied to Royal Navy results. The strategic imbalance was that Britain could reroute much of its traffic around Africa when the direct Mediterranean route became too dangerous. Italian North African supply lines had no comparable alternative, leaving them persistently exposed to Royal Navy interdiction even when individual convoys arrived.
