The Dispositie (operation order) of 22 May 1896 — Operatiën tegen de VI Moekims — signed by Kolonel Stemfoort at Koeta Radja on 22 May 1896 and preserved in the narrative of Kruisheer’s ATJEH ‘96 — was the formal operation order specifying the disposition of the four colonnes and the reserve for the major Dutch offensive of 23 May 1896 against Teuku Umar’s stelling in the VI Moekims. The dispositie detailed the composition, objective, and march route of the Bergcolonne (mountain column) under Lt.-Col. Van Heutsz, the Colonne Lamtih under Lt.-Col. Laceulle, the Colonne Djeroe Loeng under Lt.-Col. Veeren, the Colonne tegen de XXII Moekims under Maj. Van der Noordaa, and the Reserve Colonne. It was the operational predicate of the Slag bij Tjot Tjako, the Slag bij Lam Asan, and the capture of Lam-Pisang and Umar’s house that broke the back of Umar’s stelling.

Background

By 22 May 1896 the strategic situation had reached the moment for which the Regeeringscommissaris had been waiting since his arrival on 7 April 1896. The buitenlinie had been abandoned; Umar had been formally dismissed by the 11; the Proclamation of 27 April 1896 had announced military operations against him; and the Bombardment of Lampisang had run for nearly four weeks at the cost of some 7,996 projectiles, to “zeer gering” (very meagre) effect. Reinforcements had arrived from Java: the 5e and 7e Bataljons had landed with the 1e Bergbatterij and a peloton cavalerie on 1 May 1896.

Intelligence on Umar’s stelling in the VI Moekims had been accumulating since the defection of two of Umar’s followers to Hr. Ms. Nias on 2 May 1896 and the ongoing reports of the controleur 1e Luit. Neelmeijer. The stelling comprised a complex of versterkingen (fortifications) and loopgraven (trenches) running from the strand west of the former blokhuis Pagani to the versterking at Binasa Lam Me, including Koeta Sagoi, wachthuizen, and versterkingen at Lam Awi, Lam Tengah-Oost, Lam Manjang (with lilla — a swivel gun), and Lam Isi. The disposition of the four colonnes and the reserve was designed to break this stelling along its entire length.

Content

The dispositie is signed by Kolonel Stemfoort (as Mil. Comd’. van A. en O. — Military Commander of Atjeh and Dependencies) at Koeta Radja on 22 May 1896 and is the formal order of battle for the 23 May 1896 attack. It specifies, in the standard Dutch operational format, the main attack, secondary attack, centre, reserve, and the staff assignments and logistics for each colonne.

The Bergcolonne (Mountain Column) under Lt.-Col. J. B. van Heutsz was assigned the storming of the Tjot Tjako height, the dominant tactical feature of the stelling; its operations on 23 May 1896 are documented in the Berichten No. 1–4 from Van Heutsz. The Colonne Lamtih under Lt.-Col. C. J. Laceulle was assigned operations against the Lamtih sector. The Colonne Djeroe Loeng under Lt.-Col. Veeren was assigned the assault on Lam Asan and the adjacent kampongs. The Colonne tegen de XXII Moekims under Maj. Van der Noordaa was assigned a feint against the XXII Moekims sector, to fix Umar’s forces there. The Reserve Colonne was held back for exploitation.

An annex to the dispositie — the Reports and observations concerning the left wing of the enemy stelling — described the enemy fortifications in detail, from the strand approximately 500 m west of where the blokhuis Pagani had stood to the versterking at Binasa Lam Me, including Koeta Sagoi, wachthuizen, and versterkingen at Lam Awi, Lam Tengah-Oost, Lam Manjang (with lilla), Lam Isi, and the connecting loopgraven. This annex, on page 178 of ATJEH ‘96, is the most detailed single Dutch source on the structure of Umar’s stelling.

Reception and Aftermath

The dispositie was executed on 23 May 1896. The Bergcolonne under Van Heutsz stormed Tjot Tjako in the early morning, and the four sequential Berichten from Van Heutsz — beginning at 6:40 a.m. with the report that the height was “niet beklimbaar voor artillerie” (not climbable for artillery) and ending at 9:15 a.m. with the report that Lam Pisang was abandoned and many Acehnese were fleeing southward — drove the operational decisions of the day. The gevecht bij Lam Asan under Maj. Veeren and Maj. Jacobs and the gevecht bij Lam Manjang en Lam Isi under Lt.-Col. Soeters proceeded on parallel axes. On 24 May 1896 Umar’s house at Lam-Pisang was captured, and on 25 May 1896 the final storming of Daman–Lam Tjroeng–Lam Poelau completed the rupture of the stelling.

Significance

The dispositie of 22 May 1896 is the operational predicate of the three-day Dutch offensive of 23–25 May 1896 — the decisive Dutch operation of the first semester of 1896 and the action that broke Umar’s stelling and drove him into retreat to Lepong. Its detailed specification of the four colonnes and the reserve, and its annex describing Umar’s versterkingen, are the primary Dutch source for the structure of both the Dutch attack and the Acehnese defence. As a historical document, the dispositie is preserved in the narrative of pages 136, 137, 178 rather than in the Bijlagen — its operational rather than political character kept it out of the official annexes, but its importance to the narrative required its full preservation in the text.
