Yerevan April 2nd, 1921
The Soviet army was back in control of the city having pushed the Armenian rebels out of it. But the revolt was not over as the rebels retreated to the mountains proclaiming the republic of Mountainous Armenia in April 26th.
Western Anatolia, April 7th, 1921 (old calendar)/April 20th, 1921 (new calendar)
Greece had spent the winter months preparing for what it hoped would be the decisive battle of the war. Six classes of reservists, the 1903, 1904, 1912, 1913, 1914 and 1915 ones had been mobilized in January and February 1921, adding nearly 137,000 men from old Greece [1], and 19,500 men from Ionia to the army bringing its total strength to 359,337 men. More than two thirds of them, almost 253,000 men had been deployed in Asia Minor and another 23,000 would be sent there over the next couple of months. [2] Even if one subtracted the 63,000 men and 61 artillery pieces that covered Greek rear areas and communication lines the Greek Asia Minor army still had 12 infantry and 1 cavalry divisions with almost 190,000 men and 452 artillery pieces available for the offensive.
The Turkish nationalists had not been idle either. Everything humanly possible had been done during the winter to reinforce the army facing the Greeks while having to deal with problems that often looked insurmountable as the Ankara government was also having to fight the French army in Cilicia and deal with a hostile Britain, with only the Soviets and Italy supporting it. Still thanks to concerted efforts the Turkish Western Front opposing the Greek army was fielding 12 infantry and 3 cavalry divisions in its northern an southern commands with about 70,000 men and 140 artillery pieces. [3]
Now the time of battle had come, as the Greek Smyrna army corps under
Dimitrios Ioannou charged out of the Akpınar-Kovalca line it had captured back in December towards Eski Sehir which was being defended by the Turkish Western front under
Ismet pasha. Further to the south the main body of the Greek army with A and B corps under the direct command of
Leonidas Paraskeuopoulos, attacked out of Usak towards Banaz and Dumlupinar against the Turkish southern command of the Western front under
Refet Bey with a supporting divisional sized drive towards Gediz. While after taking Dumlupinar a covering force was to continue towards Afyon Karahisar, the bulk of the attacking force was to wheel north towards Kutahya and Eski Sehir to meet the northern prong of the offensive under Ioannou, trapping the Turkish army between them. Now it was to be seen how well the plan would survive contact with the enemy...
Addentum: Maps
The linked map below is from the excellent
http://mikrasiatikhekstrateia.gr specifically the article here:
http://mikrasiatikhekstrateia.gr/epixeiriseis/augoustos21/apofasi_epixeiriseon_pros_Agkura and shows the OTL battles of Kutahya-Eskisehir in July 1921. While it does not exactly match the TTL spring offensive it is substantially similar. Roughly:
- The Smyrna Army corps is attacking along the lines showing here for III and XI divisions (in blue). But TTL it is already in contact and slightly to the east of Bozuyuk, "Κοβαλίτσα" in the map is Kovalca. And this is the main corps effort with all divisions and corps assets.
The Archipelago division is the VII shown in the map (it was renamed after the November election). TTL it's a single division push in support of the main effort at Inonu Edit: Upon further thought this route is not used at all. Makes no sense to do so with the Greeks already in the Avgin-Kovalca line since January. Well it did not make much sense in OTL come down to this to put two divisions through effectively no roads.
- The southern prong of the attack is more or less the same.

[1] In OTL the Royalist government mobilized the same classes in March and April 1921 recruiting about 111,000 more men, but allowed widespread draft evasion in central Greece and the Peloponnesus that were primarily royalist. TTL no excuses are taken, the mobilization may not go to the extremes of 1917-18 at the height of the national schism when the Royalist actively tried to sabotage it and the Venizelist government answered by public executions of deserters, but still is enforced the same all over the country recruiting some 26,000 men more.
[2] In OTL out of 328,000 men in June 1921 128,000 were retained in Europe on various excuses although a number of them would be later sent to Anatolia, the Asia Minor army was up to 224,000 by April 1st, 1922. Here the number of troops back in Europe is kept at the OTL April 1921 levels (slightly below 107,000 men) and is then further reduced to 84,000 the OTL March 1921 levels.
[3] Rifle strength is of course significantly lower for both the Greek and Turkish armies as the numbers here is total strength but still the Greeks have roughly a 2,5- 3:1 numerical superiority in infantry (~119,000 to ~46,000) and artillery (452 to 140 guns) while being somewhat inferior in cavalry (~3,500 against ~4,500)
[4] Source is the map 69, in book 3 of the Turkish army's Western front's official history for April 15th, 1921
[5] This one is in Trebizont in the map I assume here it was still under Eastern front command
[6] Kocaeli group most probably
[7] By April 15th 11th and 24th infantry are showing as probably reserve in the southern group. Since they were in the thick of the fighting during 2nd Inonu just before this in OTL, I suspect they had been pulled from the line to reorganize so left them still in the north TTL.
[8] These may be directly under Western front command and by July were for certain in the 1st, 3rd and 4th "groups of divisions" themselves, but the map is not showing something beyond an army level command.
[9] Rear area units excluded. I also make the assumption that the older De Bange 120mm guns and BL 6-inch 30 cwt have been placed in reserve to provide trained manpower for the heavy artillery provided by Britain. Rear area units artillery would be as follows:
Krupp M1904 Mountain gun 75mm: 10
Krupp M1904 field gun 75mm: 15
Schneider M1906 75mm: 6
Schneider M1904 75mm: 22
Schneider M1907 75mm: 8
