Battle of Arica and Flag Day

The holiday marks the Battle of Arica, fought on 7 June 1880 during the War of the Pacific (1879–1883) between Peru and Bolivia against Chile. After Chile's victory at the Battle of Tacna on 26 May 1880, the port of Arica became the last Peruvian stronghold in the south. Chilean forces under General Manuel Baquedano surrounded the city and demanded its surrender.

Colonel Francisco Bolognesi, commander of the Peruvian garrison, famously replied that he had sacred duties to fulfil and would fight until the last cartridge was spent. On 7 June 1880 Chilean troops assaulted the Morro de Arica, the steep headland guarding the port. In a few hours of brutal fighting the Peruvian defenders, including Bolognesi and the young captain Juan José San Martín, were killed; Bolognesi died in hand-to-hand combat. Arica fell to Chile and, under the 1883 Treaty of Ancón and the 1929 Treaty of Lima, remained Chilean territory.

Peruvian law established 7 June as the Día de la Bandera (Flag Day), a national holiday honouring the defenders of Arica and the Peruvian flag. The date ties patriotic remembrance to the flag itself, since the flag was raised over the Morro and became a symbol of the sacrifice of Bolognesi and his men. The Battle of Arica is also commemorated as one of the defining episodes of the war, alongside the naval campaign and the defence of Lima.

On 7 June each year, public institutions, schools and military units across Peru hold flag-raising ceremonies, parades and solemn acts. Schoolchildren recite the national pledge of allegiance to the flag and take part in civic processions, often dressed in school uniforms or historic military garb. Government buildings and many homes display the red-and-white Peruvian flag, sometimes with black mourning ribbons in memory of the fallen.

In Lima, ceremonies are held at the Plaza Bolognesi, where a monument honours Colonel Bolognesi, and at the Pantheon of the Heroes, where his remains and those of other war dead rest. Military honours, wreath-laying and speeches recounting the siege of Arica are standard. Schools organise essay and poetry contests about the battle, and local authorities in provincial towns combine the flag ceremony with civic parades.

Because 7 June is a public holiday, many Peruvians enjoy a long weekend. Families gather for traditional meals such as pollo a la brasa, anticuchos or a hearty stew like seco de cordero; in the Andean regions, meals may feature cuy or pachamanca. In Arica itself, now in Chile but still home to a Peruvian community and the historic Morro, commemorations draw Peruvian residents and visitors, and the date remains an emotional touchstone for those with ties to the lost province.

The holiday commemorates the sacrifice of Colonel Francisco Bolognesi and the defenders of Arica, who chose death over surrender. It honours a central episode of the War of the Pacific and reinforces the Peruvian flag as a symbol of national unity and resistance. Bolognesi, declared Patron of the Peruvian Army, embodies duty and honour, and the phrase attributed to him — that he would fight until the last cartridge — is taught to schoolchildren as a model of patriotism.

Flag Day also carries a broader civic meaning. It invites Peruvians to reflect on national sovereignty, the memory of the war's territorial losses in the south, and the ties to Arica that persist culturally and emotionally. The date is used by schools and institutions to teach the nation's history and to foster respect for national symbols, making it both a solemn remembrance of the dead and an affirmation of Peruvian identity.
