What happened July 1991 AD

The YPA's ammunition dump at Črni Vrh caught fire and was destroyed in a massive explosion, damaging much of the town.

More skirmishes took place, with Slovenian TO forces taking over a YPA facility at Nova vas, south of Ljubljana.

The Slovenians successfully captured depots at Pečovnik, Bukovžlak, and Zaloška Gorica, taking possession of some 70 truckloads of ammunition and explosives.

The YPA 306th Light Air Defense Artillery Regiment's column retreated from its exposed position at Medvedjek and headed into the Krakovo Forest (Krakovski gozd) near the Croatian border. It ran into a blockade near the town of Krško and was surrounded by Slovenian forces, but refused to surrender, probably hoping for help from a relief column.

In July 1991, representatives of the Serb Democratic Party (SDS), including SDS president Karadžić, and Muhamed Filipović and Adil Zulfikarpašić from the Muslim Bosniak Organisation (MBO), drafted an agreement known as the Zulfikarpašić–Karadžić agreement which would leave SR Bosnia and Herzegovina in a state union with SR Serbia and SR Montenegro. The agreement was denounced by Croat political parties. Although initially welcoming the initiative, Izetbegović later dismissed the agreement.

the YPA's leadership sought permission to change the tempo of its operations. Defense Minister Veljko Kadijević informed the Yugoslav cabinet that the YPA's first plan – a limited operation to secure Slovenia's border crossings – had failed, and that it was time to put into operation the backup plan of a full-scale invasion and imposition of military rule in Slovenia. >>the collective presidency (Yogoslavia)– headed at the time by Serbia's Borisav Jović – refused to authorise such an operation. The YPA Chief of Staff, General Blagoje Adžić, was furious and publicly denounced "the federal organs [which] continually hampered us, demanding negotiations while they [the Slovenians] were attacking us with all means".

Nokia assisted in the development of the GSM mobile standard in the 1980s, and developed the first GSM network with Siemens, the predecessor to Nokia Siemens Network. The world's first GSM call was made by Finnish prime minister Harri Holkeri on 1 July 1991, using Nokia equipment on the 900 MHz band network built by Nokia and operated by Radiolinja.

The Slovenian TO mounted successful attacks on border crossings at Šentilj, Gornja Radgona, Fernetiči and Gorjansko, overrunning them and taking a number of YPA troops prisoner.

The heaviest fighting of the war to date took place during 2 July. The Domžale radio transmitter was attacked at (11:37 local time) and heavily damaged by two YPA Mig-21 planes.

At 21:00, the Slovenian Presidency announced a unilateral ceasefire. However, this was rejected by the YPA leadership, which vowed to "take control" and crush Slovenian resistance.

A large YPA armoured convoy set off from Belgrade on the morning of 3 July, ostensibly to go to Slovenia. It never arrived; according to the official account, this was due to mechanical breakdowns.

With a ceasefire now in force, the two sides disengaged. Slovenian forces took control of all of the country's border crossings, and YPA units were allowed to withdraw peacefully to barracks and to cross the border to Croatia.

The Ten-Day War was formally ended with the Brioni Accord, signed on the Croatian Brijuni Islands. Slovenian and Croatian independence were agreed to.
