ST-29 was the codename for a Syaran convoy during the Siduri War. On 16 October 1936 the convoy of cargo ships carrying raw materials from the neutral states of Silua and Shalum departed from their rendezvous in the Malian Sea and began sailing for Syara. The Cacertian Royal Navy, having learned of the convoy and its intended route through the Ruvelkan Resistance, dispatched a cruiser division including the Dino Calvini-class battlecruiser HMS Nofri Calza, commanded by Division Admiral Marina Firavanti to intercept. The Navy of the Syaran Republic learned of Cacertian intentions and in turn dispatched the Galania-class battleship RS Calm and Penance and a task force of cruisers, submarines, and destroyers to help protect the convoy.

The Cacertian cruiser force made contact with the convoy at 08:23 on 17 October and briefly engaged, sinking one cargo ship. The engagement allowed the Syaran pursuit force led by the Calm and Penance to arrive on the scene and engage the Cacertian flotilla. In the ensuing battle both sides suffered losses as the Calm and Penance was sunk after a four hour long battle with the Cacertian cruisers, three of whom were sunk alongside the battlecruiser Nofri Calza. Only the Scarano-class cruiser HMS Cantaso managed to break contact and retreat south back to friendly waters. Although they had managed to sink a Syaran battleship, the loss of three cruisers and a battlecruiser led the Cacertian Admiralty to issue new orders and protocols regarding convoy raids near the Sanguine Sea.
