Operation Endowment - 43 Commando Royal Marines
Unit/ Formation: 43 Cdo RM
Period/ Conflict: World War II
Date/s: 22 March 1944
On the 22nd – 23rd March 43 Commando raided the island of Hvar with a force of partisans, attacking German garrisons.
Until the end of 1943, German forces were advancing into Dalmatia after the capitulation of Italy. Starting in late 1943, the Allies undertook a major evacuation of civilian population from Dalmatia fleeing the German occupation, and in 1944 moved them to the El Shatt refugee camp in Egypt.
By 1944, only the island of Vis remained unoccupied by the Germans, and Yugoslav and British troops were tasked with preparing its defenses against the later cancelled German invasion (Operation Freischütz). The island was about 14 miles long and 8 miles wide, with a mainly hilly outline, and a plain in the centre covered with vines, part of which had been removed to make way for an airstrip about 750 yd (690 m) long, from which four Spitfires of the Balkan Air Force were operating. At the west end of the island was the Port of Komiža, while at the other end was the Port of Vis; these were connected by the only good road running across the plain. Vis was organized as a great stronghold, held until the end of World War II.
In 1944 Tito's headquarters moved there, and eventually over 1,000 British troops were included in the defence of Vis. British forces on the island were called Land Forces Adriatic, and were under the command of Brigadier George Daly. The force consisted of No. 40 and No. 43 (Royal Marine) Commando of the 2nd Special Service Brigade, the 2nd Bn. The Highland Light Infantry, and other support troops. Operating from the two ports were several Royal Navy craft. Marshal Tito's forces numbered about 2,000. Vis was functioning as the political and military center of the liberated territories, until the liberation of Belgrade late in 1944.
British naval forces in the Middle East operating in the Adriatic Sea were under the command of the Flag Officer Taranto and Adriatic & Liaison with the Italians (F.O.T.A.L.I). All the naval forces were controlled from Taranto and operated in close coordination with the Coastal attack operations conducted by the BAF. The Yugoslavs used the units in the British navy to transport materials and men, but especially to make landings on the islands of Dalmatia to liberate them from German occupation.
During the Vis period, Partisans carried out several seaborne landings on Dalmatian islands with help of Royal Navy and commandos:
Šolta – Operation Detained
Hvar – Operation Endowment
Mljet – Operation Farrier
Brač – Operation Flounced
Operation Endowment 
German 2nd Panzer Army decided to withdraw 2nd Battalion of the 738th Regiment from 118th Jager Division from Jelsa on Hvar island and to leave only its 8th Company in Sućuraj guarding the eastern half of the island. This was carried out by night using landing barges and crafts because of Allied air power which on 15 March managed to sink landing barges SF-102 and SF-276 landing craft I-72 in Jelsa slowing down German progress. 8th Company was delayed leaving Jelsa until evening of 22 March just before it was attacked.
Based on these intelligence reports it was immediately decided to launch a raid with newly arrived 43rd Commando and capture Jelsa before German 8th Company can withdraw expecting another easy victory like on Šolta island in operation DETAINED. This is the reason Allies rejected aid of 26th Dalmatian division in the operation but staff decided to land 400 soldiers of the 1st and 4th battalions from 1st Dalmatian Brigade based on request from operational officer which was already on the island together with group of Allied officers.
Ships left Vis island in the afternoon of 22 March 1944.
280 commandos, which arrived on Hvar in theirs LCI before NOVJ two battalions which where using old motor sail boats: 'Slobodan', 'Jadran', 'Sretna Sloboda', 'Sokol' and 'Lahor', were careless and got discovered and pinned down by the Germans next to a minefield. Being late arriving at their positions near Jelsa bombing raid by air force from 16:30 to 17:00 there was only 74 commandos available to engage Germans who were already withdrawing from Jelsa. Germans took control of surrounding high ground allowing them to encircle commandos and to fall back to Sućuraj. Arrival of NOVJ battalions broke German encirclement and after two hour combat smashed German column.
Next day was spent chasing remaining German troops across the island with commandos clearing eastern and Partisans western half of the island. In the evening on 23 March commandos decided to leave the island leaving only Yugoslav Partisans to continue clearing operation.
During the night of 23/24 March Germans landed two companies at SuÄ‡uraj to receive their 8th Company which by now was destroyed instead they ran into Partisan 4th Battalion at Bogomolj in the evening on 24 March which fell back after a fight. While withdrawing battalion noticed German assault boat I-69 which was damaged by allied aircraft in Bristova cove and captured 5 sailors. On the 25 March island was split with Germans holding eastern half to Bogomolj while Partisans had 4th Battalion in Pitavska PlaÅ¾a and 1st In Brusje.
On 22 March from 18:45 to 19:15 Luftwaffe sent 12 aircraft to bomb port of KomiÅ¾a on Vis leaving 3 dead and 33 wounded, sinking Partisan patrol boat PÄŒ-70 and damaging several other ships.
Immediately after destruction of the 9th Company, German 2nd Panzer Army wanted to launch counterattack but there wasn't enough ships to transport troops quickly enough. Also there was no major German surface units in the area which could block Yugoslav Partisan Navy from moving troops and supplies between Vis and Hvar.
With reports that Germans are preparing a major landing on Hvar it was decided to withdraw two remaining battalions back to Vis and on night of 28/29 March 420 soldiers and 437 refugees were evacuated with further 16 soldiers and 47 refugees on the following night. Only smaller Partisan detachment was left on Hvar island.
With reinforcements arriving on 27 March Germans started slowly to advance towards Jelsa and during night of 29/30 March from Sumartina made landing near Jelsa and on 1 April took control of Stari Grad.
On Hvar island Germans suffered 32 killed (30 soldiers, 2 officers) and 152 captured (2 officers), while Partisans suffered 3 dead and 20 wounded. Commandos who had 3 wounded have captured only 8 Germans soldiers.
Partisans also captured 5 machine-guns, 127 rifles, 9 sub-machine guns, 13 pistols, 2 semiautomatic rifles and large amounts of ammunition, medical supplies and other material. Also allied aircraft sunk large number of German landing crafts and barges which was serious blow to German navy in Adriatic.
DETAINED and ENDOWMENT forced Germans to make changes in island defense, their garrisons were no longer located in requisitioned school buildings and other buildings in villages where they could be easily surrounded and were easy target for air force. Now garrisons were moved to strategic high ground with stone trenches protected by barbed wire and land mines with quick reaction force on the mainland ready to move quickly with reinforcements to threatened island.
This made future operations much more costlier for the Allies but it achieved primary goal of these raids - it forced Germans to commit large number of troops and other resources to coastal defense.
