A landing attempt in Sollum made by a cruiser during the night 14/15 April remained unsuccessful. Also during the night 15/16 April an enemy raid on Sollum with heavy artillery, naval, and air support was repulsed. Own losses 45 men. Only a permanent patrol was left in Sollum due to continuous enemy fire. Continuous air attacks and fire from naval units caused losses to Gruppe Herff.
Written directive to Gruppe Herff regarding offensively organised defense of Sollum see the same.
Early morning reconnaissance by Fliegerfuehrer Afrika noted that 2 transports had left the port of Tobruk. An attack on the large enemy naval unit reported off Bardia and Sollum was not possible due to dust storm.

This was the so-called battle of the Tarigo convoy, named after the command vessel of the escort, Navigatori-class destroyer Luca Tarigo. The whole convoy was lost, including all the escorts. The destroyer’s commander, Commander Pietro de Cristofaro, and its Chief Engineer, Luca Balsofiore, received posthumous Gold Medals for Valor for the action, during which Tarigo sank the Tribal-class destroyer HMS Mohawk. More detail on the battle, and the shifting historical views, can be found at this link, this link, and this link. The Italian Wikipedia (at this link) has good maps.
Luca Tarigo pre-war, after the first set of structural modifications, showing quite well the forward and centre twin-turrets with their 120mm guns.
Some of the material was recovered later, since all the vessels sank in shallow waters. Signals battalion 33 also had two command tanks on strength.
The whole desaster is quite well described on p.164 onwards of the Official History of the Australian Army, at this link (opens PDF)
